Question

The activation energy of an endothermic reaction _____.

1. must be greater than the required ΔH
2.must be less than the required ΔH
3.must be equal to the required ΔH
4.is not needed for the required ΔH

Answer 1

It must be greater.

Step-by-step explanation:

I just took the quiz.

Answer 2

Endothermic reactions are reactions that require heat in the course of the process. The heat of reaction in this case is positive which means the energy of the products is greater than the energy of the reactants. In this case, the answer to this problem would have to be 1. must be greater than the required ΔH
