Which statement is Hess’s law?

Correct answer A. The total enthalpy change of a reaction is the same whatever route is taken, provided the initial and final states are the same

Explanation

Hess's law follows from enthalpy being a state function. It allows enthalpy changes that cannot be measured directly to be calculated by combining other known reactions in an energy cycle.
