If different processes are used to bring about the same chemical reaction, the enthalpy change is same for all of them. This is __________ law.

A Hess's
B Kirchoff's
C Lavoisier and Laplace
D None of these

Correct Answer: Hess's

Hess law : if different process are used to bring the same chemical reaction than the enthalpy change is same for all of them.
(Note : enthalpy is a point function doesn’t depends on the path between.)
