How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
What effect does an enzyme have on Ea?
Enzymes lower the activation energy (Ea) required for a chemical reaction to occur. By binding to reactant molecules and stabilizing the transition state, enzymes facilitate the formation of products from substrates. This acceleration of the reaction reduces the amount of energy needed to initiate the reaction, making it more favorable and allowing it to occur at a faster rate.
How does the catalyst and inhibitors affect the rate of chemical reaction?
Catalyst ensures that the activation energy of the molecules is lowered so there is effective collisions,and it does this in two ways;the transition and absorbtion states but inibitors even raises the activation energy and causes in effective collisions.
What does a catalyst do in a chemical reaction?
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
The addition of a increases the rate of reaction by providing an alternative pathway with a lower activation energy?
A catalyst, like enzymes.A catalyst is a substance that lowers the activation energy for a reaction and allows the process to speed up. The catalyst does not react with the substance so that it is 'used up'; in other words, it's reusable and comes out of the reaction unchanged.
What chemical reduces the amount of activation energy needed for a reaction but is not a reactant?
Enzymes catalyze certain reactions.
Do enzymes work by providing energy to initiate reaction?
No they do not supply energy to start a chemical reaction, however energy has something to do with it. Enzymes actually lower energy barriers, in other words it reduces the activation energy needed which is the energy absorbed before the chemical reaction can start.
How does the interaction between an enzyme and its substrate change a chemical reaction?
Enzymes speed up the chemical reactions because when it forms a complex with its substrates, it reduces the activation energy that the reaction needs to proceed. Remember that the reaction itself is not altered, only the rate of reaction, and that the enzyme is not used or altered in the reactions.
Ensymes are usually what?
Enzymes are usually something that reduces a chemical reaction.
How does a enzyme increase the speed of a reaction?
The enzyme reduces the activation energy of the reaction, therefore chemical reaction speeds are increased.
Describe how the interaction between an enzyme and its substrates change a chemical reaction?
Enzymes speed up chemical reactions because when it forms a complez with it's substrate, it reduces activation energy.
How does the interaction between an enzyme and its substrates change chemical reaction?
Enzymes speed up the chemical reactions because when it forms a complex with its substrates, it reduces the activation energy that the reaction needs to proceed. Remember that the reaction itself is not altered, only the rate of reaction, and that the enzyme is not used or altered in the reactions.

When a catalyst is present and more or less activation energy is needed to start a chemical rection?
A catalyst reduces the amount of activation energy needed to start a chemical reaction.
What is enzyme and what is the function?
Enzymes are substances that increase the speed of a chemical reaction. 1. A substrate attaches to an enzyms's active site. 2. The enzyme reduces the activation energy of the reaction. 3. The enzyme is not changes by this reaction. That is how a Biology book explains it. I hope that helps you.

How does enzymes catalyze a chemical reaction?
by lowering activation energy to increase the reactionEnzymes are biological catalysts, and can hence lower the activation energy barrier of the reaction that it catalyses. Enzymes do this in several ways:1) Enzymes can provide a suitable environment for the reaction to take place. The active site of a enzyme can be highly acidic (pH
