Catalysts accelerate a reaction by ________.
Catalysts accelerate a reaction by ________.
Homework Answers
- Catalysts are molecules or substance that helps in catalysing a chemical reaction.
- Catalysts help to increase the rate of chemical reactions.
- A catalyst reduces the activation energy or the minimum energy required by a chemical reaction to take place. This causes an increase in rate of reaction.
- So we can say that catalysts accelerates the reaction by lowering or decreasing the activation energy of a chemical reaction.

Catalysts are molecules that can speed up the rate of a reaction and are regenerated, this allows for effective catalysts to be used in very small quantities with respect to the substrate being transformed. This experiment uses copper acetate as a catalyst at about 12% loading with respect to benzoin. Calculate the amount of copper acetate used to convert 1.130 g of benzoin to benzil, if the catalyst loading is
