Select the correct answer. How does activation energy affect a chemical reaction?

A. It increases the energy of the reactants.
B. It determines how difficult it is to start the reaction.
C. It determines how much product can form,
D. It decreases the energy of the products,

The source of the activation energy needed to push reactions forward is typically heat energy from the surroundings.

Explanation:

The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be
