Question

Activation energy is ____. (1 point)

(0 pts) the heat realeased in a reaction
(0 pts) the energy barrier between reactants and products
(0 pts) the energy given off when reactants collide
(0 pts) generally very high for reaction that takes place reapidly

Answer 1

Activation energy is the energy barrier between the reactants and products.

Answer 2

Activation energy is defined as the least amount of energy that is needed to be available in a chemical system with potential reactants in order to result a chemical reaction. Therefore, the correct answer would be the first option: the heat released in a reaction.
