Question

What does Hess's law state about the total enthalpy change for a reaction?OA. It depends on the reaction pathway.B. It can only be calculated from the equilibrium constant.C. It must be determined experimentally.D. It is independent of the reaction pathway.

Answer 1

Option D is correct. It is independent of the reaction pathway.

Explanations:

What is Hess's law?

Hesslaw states that the enthalpy change of a reaction does not change regardless whether the reaction takes place in a single or multiple reaction pathways.

This shows that the total entalpy change of a reaction does not depend on the reaction pathway.
