Hess's law states that the standard enthalpy change for a reaction:
ADepends on the path taken between reactants and products fully
BEquals the temperature times the entropy change for any path
CIs zero for spontaneous reactions in a chemistry lab cycle
DDepends only on initial and final states, not on the path taken
Answer & Solution
Correct answer: D. Depends only on initial and final states, not on the path taken
Enthalpy is a state function; Hess's law says $\Delta H$ is path-independent.
