How do catalysts generally affect chemical reactions? A They increase the temperature of the system. B They increase the surface area of the reactants. C They increase the activation energy by introducing enzymes. D They lower the activation energy by providing an alternate pathway.

A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without itself being consumed by the reaction.

Activation energy is the minimum amount of energy required for a chemical reaction to proceed in the forward direction.

A catalyst increases the reaction rate by providing an alternative pathway or mechanism for the reaction
