Question

Which best describes the activation energy of a chemical reaction?

A. the combined energy of all the reactants
B. the amount of energy required for a reaction to occur
C. the difference in energy between products and reactants
D. the potential energy stored in the bonds of reactants and products

Answer 1

The answer is B as activation energy is the least possible amount of energy (minimum) which is required to start a reaction or the amount of energy available in a chemical system for a reaction to take place.

Answer 2

The answer would be B.

The amount of energy needed to “activate” a reaction or for it to occur.
