Question

Catalysts, including enzymes, have the role of Select one: a. changing a nonspontaneous chemical reaction to spontaneous. b. lowering the activation energy of a reaction. c. heating up the reactants to make the reaction progress faster. d. changing the pH to a favorable pH for the reaction to progress.

Answer 1

Lowering activation energy of a reaction.

Step-by-step explanation:

Activation energy is the minimum amount of energy required by the reactants just to be converted to products.

Since catalysts increase the rate of reaction, activation complex is reached in short period of time hence activation energy is lowered.
