Q:Can you describe at least 4 ways a catalyst can lower the activation energy of a reaction?
To see how a catalyst accelerates the reaction, we need to look at the potential energy diagram shown below which compares the non-catalytic and the catalytic reaction. For the non-catalytic reaction, the figure is simply the familiar way to visualize the Arrhenius equation: the reaction proceeds when A and B collide with succificient energy to overcome the activation barrier. The change in Gibbs free energy between reactants, A + B, and the product P is delta G. The catalytic reaction starts by bonding of the reactants A and B to the catalyst, in a spontaneous reaction. Hence, the formation of this complex is exothermic and the free energy is lowered. There then follows the reaction between A and B while they are bound to the catalyst. This step is associated with an activation energy; however, it is significantly lower than that for the uncatalyzed reaction. Finally, the product P seperates from the catalyst in an endothermic step. The energy diagram illustrates 4 ways the catalyst works : The catalyst offers an alternative path for the reaction that is energetically more favorable The activation energy of the catalytic reaction is significantly smaller than that of the uncatalyzed reaction; hence the rate of the catalytic reaction is much larger The overall change in free energy for the catalytic reaction equals that of the uncatalyzed reaction. Hence, the catalyst does not affect the equilibrium constant for the overall reaction. A catalyst cannot change the thermodynamics of a reaction but it can change the kinetics. The catalyst accelerates both the forward and the reverse reaction to the same extent. In other words, if a catalyst accelerates the formation of product P from A and B, it will do the same for the decomposition of P into A and B.
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:High chemistry: Does the catalyst affect the heat and heat of the reaction?
No effect
Q:What is the difference between a catalyst and an inducer in a chemical reaction?
The catalyst does not participate in the reaction, but only the carrier of the reaction; the inducer will participate in the reaction
Q:Can a catalyst react with a reactant?
it can react to start the reaction but should be regenerated during the reaction. if it reacts and not regenerated,then its better to call it reactant instead of catalyst
Q:Several experiments were carried out using catalysts
Hydrogen peroxide in the manganese dioxide as a catalyst for decomposition reaction: 2H2O2 == MnO2 == 2H2O + O2 ↑ (laboratory oxygen principle)
Q:Comparison of biocatalysts with chemical catalysts!
The same point: biocatalysts and chemical catalysts are selective (specific) and efficient; participate in each reaction, its own nature and quantity will not change.
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:Explanation of Catalysts?
A catalyst provides an alternative reaction pathway with a lower activation energy. So it speeds up the rate of reaciton because the energy of the particles/reactants doesnt have to be that high to OVERCOME the activation energy so it can therefore react. The activation energy is the minimum amount of energy required for particles to react, so the lower it is, the more faster a rate of reaction will be.
Q:what is the difference between enzyme and catalyst?
Enzymes and catalysts both affect the rate of a reaction. The difference between catalysts and enzymes is that while catalysts are inorganic compounds, enzymes are largely organic in nature and are bio-catalysts. Even though all known enzymes are catalysts, all catalysts are not enzymes. Moreover, catalysts and enzymes are not consumed in the reactions they catalyze. Catalysts are low molecular weight componds, enzymes are high molecular globular proteins. Catalysts are inorganic, enzymes are organic. Catalyst reaction rates are slower (usually) than enzyme reaction rates. Catalysts are not generally specific - enzymes are VERY specific. Catalysts increase or decrease the rate of a chemical reaction, enzymes are proteins that incrase the rate of chemical reactions & convert the substrate into product. There are 2 types of catalysts - (positive & negative), and the 2 types of enzymes are activation enzymes and inhibitory enzymes. Catalysts are simple inorganic molecules, while enzymes are complex proteins.
