Q:Brief introduction of enzyme as biocatalyst and general chemical catalyst and its personality
can only change the rate of chemical reaction, do not change the equilibrium point of the chemical reaction, the enzyme itself does not change before and after the chemical reaction (3) can reduce the chemical reaction of the activation energy The
Q:Chemistry GCSE what is a catalyst?
A catalyst is a substance added to a reaction to speed the reaction up!
Q:What is a catalyst/catalase? help?
an enzyme that decomposes hydrogen peroxide into oxygen and water.a substance that causes or accelerates a chemical reaction without itself being affected. To put thing simply, a catalyst is any substance that speeds up a chemical reaction. These can be natural or manmade. Catalase is actually a specific type of naturally-occuring catalyst, an enzyme in cells that decomposes hydrogen peroxide (Which is extremely toxic to life!) into harmless components. Catalase enzymes are highly concentrated in the aptly named cell organelles known as peroxisomes. Just remember- if the word ends in -ase, it's a type of enzyme! :) Hope this information helps!
Q:Explanation of Catalysts?
Hi Ganah! A catalyst is a substance that increases the rate of a chemical reaction without itself being used up in the reaction. They lower the activation energy for a reaction and also speed up the rate of the reaction (both in reverse and forward reactions). Let's look at a generic chemical reaction: A + B---C + D C + D---B + E Here, the catalyst is substance B because it is part of the chemical reaction but then it is not used up in the net reaction. See how it seems to be used up in the first step, but by the second step, the catalyst is made once again. The net reaction is A + B--->B + E and you can see how it is not consumed in the reaction. There are also 3 types of catalysts. Heterogeneous catalysts are catalysts that are in different phases than the reactants. An example would be like a reaction between two solids but a liquid is added to speed up the reaction. The liquid is in a different state of matter than the solids but it can still function as a heterogeneous catalyst. Homogeneous catalysts are catalysts that are in the same states of matter as the reactants. An example would then be ethyl acetate reacting with water to form acetic acid and ethanol with an acidic catalyst. They would all be liquids. Lastly, there are enzyme catalysts. These are proteins in your body that speed up biological reactions by reacting with substrates. I hope this helped and good luck with chem!
Q:When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
No, the catalyst is written above the equal sign, not the reactants, nor the product
Q:What is the superiority of the catalyst compared to the stoichiometric reagent?
Specificity: an enzyme can only catalyze one or a class of substrates, such as proteases that catalyze the hydrolysis of proteins into polypeptides;
Q:How are a catalyst and an intermediate similar? How are they different?
A catalyst speeds up the rate of a reaction by lowering the activation energy barrier which is, presumably, the energy required to achieve the reaction intermediate. Catalysts are also not consumed in the reaction, they are regenerated towards the end. A reaction intermediate is a configuration that a molecule takes prior to achieving it's lowest energy form which would signify the end of the reaction. Intermediate usually are hard to isolate because of the incentive to go to the most stable configuration. How are they different? A catalyst is not a part of the reaction product and it doesn't get consumed. An intermediate in a reaction is transformed into the product. How are they similar? Well, catalysts drive the reaction and make it easier for the reaction for follow through. Since intermediates are high energy and thermodynamics tells us that low energy is favorable, the incentive for a high energy intermediate to drive down to it's stable for can also drive a reaction. I hope that helps. I hope it makes sense.
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:Which of the following are true about catalysts?
1, 3, 5, 6, 7. 2 is incorrect, catalysts are written above the reaction arrow. 4 is incorrect, catalysts decrease the activation energy thus increasing the rate of reaction (see 7) 8 is incorrect, catalysts are not used up (or if they are, they are also regenerated by a different reaction so that they maintain a constant concentration). edit: about 5, yes i think the answer below is correct, 5 is false actually. catalysts speed up both the forward and the reverse reaction so the equilibrium constant is unchanged. however, 1 is true i think: catalysts can provide a lower energy pathway by way of bringing the reactants together in the correct orientation (rather than random orientations).
Q:What is a chemical catalyst?
A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.
