Q:Chemistry why the catalyst can be equal to speed up the positive reaction rate
Since the catalyst only changes the activation energy and the amount of reactivity can be reduced, the amount of reaction energy is also reduced. Therefore, a positive catalyst is also a good catalyst for its reaction. Speed up the same multiple.
Q:Will the catalyst change the reaction rate in the chemical reaction?
Many of the catalysts are specific in varying degrees, and when added to the chemical reaction system that it can catalyze, it must change the rate of chemical reaction, and of course both positively and negatively catalyzed. Chemical reaction rate, it can not be called a catalyst.
Q:A biological catalyst or a chemical reaction facilitator is know as a/an?
A biological catalyst is an enzyme. Here are more details for you. Enzymes – biological catalysts Normally chemical reactions do not proceed spontaneously, but require the help of a catalyst. A catalyst accelerates a chemical reaction without itself being changed. For example, the reaction of hydrogen with oxygen to produce water requires the addition of the metal platinum. These days we encounter the concept of a catalyst most often in connection with technology for cleaning up the exhaust fumes from our automobiles, where platinum and rhodium catalyze the breakdown of polluting nitrogen oxides. Chemical reactions within living cells must also be catalyzed. Biological catalysts are called enzymes. There is, for instance, an enzyme in our saliva which converts starch to a simple sugar, which is used by the cell to produce energy, and another enzyme which degrades the excess lactic acid produced when we overexert ourselves. All green plants contain enzymes which convert carbon dioxide in the air to nutritious carbohydrates such as sugar and starch. Without enzymes life would not be possible! Enzymes are highly selective. Among the thousands of different compounds in a cell, an enzyme can recognize the right molecule (substrate) and transform it into a new product. This property arises from the special three-dimensional structure of each enzyme. One can compare an enzyme and its substrate with a lock and its key. Enzymes are very effective catalysts. A chemical reaction might require several months to reach completion without a catalyst, but only a few seconds with the help of an enzyme. Since the enzyme remains unchanged, one enzyme molecule can catalyze the transformation of millions of substrate molecules. Up until the beginning of the 1980's, all enzymes were thought to be proteins. We now know that proteins do not have a monopoly on biocatalysis. RNA molecules can also function as enzymes.
Q:If possible can anyone give me information on the active site, substrates, products, and the energy of activation as part of the answer?Responses greatly appreciated! Thankss! 10pts to best answer!
Catalysts help shift the equilibrium of a reaction to one that is more favorable. They allow a naturally occurring reaction that may be extremely slow to progress faster or an unfavorable reaction to proceed forward. During the process catalysts are recycled, which means that at the catalyst is the same compound in the beginning and the end of the reaction, although during intermediate steps catalysts can change conformation. Catalysts shift the equilibrium of a reaction by lowering the activation energy of a reaction, which is the energy barrier which must be overcome in order for the reaction to proceed in a desired direction. This can be achieved in several ways such as providing favorable thermodynamic conditions for a reaction or creating intermediates which react more favorably to create the products. Inside the cell a lot of chemical reactions are either too slow to proceed naturally or are simply unfavorable. Catalysts help overcome those barriers. The substrate is the part of the reaction which gets transformed into the products after binding to the active site of the protein.
Q:Junior high school chemistry - chemical reaction before and after the quality and chemical properties of the material must be the catalyst?
It is not always possible that the equivalent reaction, i.e. one or more of the reactants, is the same as the relative atomic mass of one or more of the products and the coefficients in the chemical equation are the same
Q:the heterogenous catalyst ZSM-5 IS used to convert ?
Zeolite-based heterogeneous catalysts are used by industrial chemical companies in the interconversion of hydrocarbons and the alkylation of aromatic compounds. A very good example is the zeolite ZSM-5. This zeolite, developed by Mobil Oil, is an aluminosilicate zeolite with a high silica and low alumininum content. Its structure is based on channels with insecting tunnels. The aluminium sites are very acidic. The substitution of Al3+in place of the tetrahedral Si4+ silca requires the presence of an added postive charge. When this is H+, the acidity of the zeolite is very high. The reaction and catalysis chemistry of the ZSM-5 is due to this acidity. The ZSM-5 zeolite catalyst is used in the petroleum industry for hydrocarbon interconversion. An example use is in the isomerizations of xylene- from meta to para-xylene. The acidic zeolite promotes carbocation isomerizations. There are two suggested mechanisms for this type of isomerizations. Firstly shape may play a role. Perhaps para-xylene has a shape which allows it to diffuse rapidly through the zeolite structure, whereas as meta-xylene takes longer to pass through the zeolite and thus has more opportunity to be converted into the para-xylene. Secondly, is that the orientation of reactive intermediates within the zeolite channels favors specifically para-xylene.
Q:Can a catalyst react with a reactant?
Catalysts are of different categories. There are some reactions, in which only the presence of some compound increases/decreases the rate of the reaction. In other examples, the catalyst do react with the reactants and provide a different path for the reaction. The product is formed and the catalyst is recovered. Not even a single molecule is consumed after the reaction. But if you take a sample while the reaction is going on, you might find a decrease in the concentration of the catalyst. (An example is the use of Mangnese dioxide (MnO2) in the conversion of Potassium Chlorate (KClO3) to Potassium Chloride and oxygen. The MnO2 added at the initiation of the reaction is in form of crystals and at the end of the reaction it is recovered as finely divided powder. This simply shows that MnO2 reacted with KClO3 initially and finally got detached in form of a powder.)
Q:and what type of macromolecule are they made of? thanks!
A catalyst is any substance that speeds up a chemical reaction without otherwise changing the outcome of the reaction. Catalysts do this by lowering a reaction's activation energy (which is the energy barrier that must be overcome before the reaction can proceed spontaneously). Catalysts are not permanently changed by the reactions they catalyze, so one catalyst could reasonably catalyze the same reaction many times over. Enzymes are biological catalysts because they lower the activation energy of metabolic reactions (and therefore increase their rate). Every enzyme has an active site that is specific for a particular substrate, or for a small related group of substrates. When the correct substrate binds to the active site, the enzyme catalyzes a particular reaction and releases new products. Substrates that don't match the shape of the enzyme's active site usually won't be affected by the enzyme. Enzymes are proteins, which are in turn polymers of amino acids. The sequence of amino acids in an enzyme, as well as the three-dimensional structure of the polypeptide chain, are essential for determining the enzyme's functionality. I hope that helps. Good luck!
Q:Before and after the reaction, the chemical properties and quality of the water did not change, and the water was the catalyst
3HIO + 3H2 = 3H2O + 3HI
Q:why is palladium/platinum a good catalyst?
I'm guessing that the answer would be heterogeneous. Hydrogenation reactions use Pt and/or Pd metal as the catalyst. But these are always solids while the reaction is between H2 and either a gas or a liquid. Consequently the catalyst is in a different phase than the reactants, making them heterogeneous. I'd go with that one.
