what does hesss law say about the enthalpy of a reaction?\na. the sum of the enthalpy and entropy is the free energy of a reaction.\nb. the enthalpy of a reaction does not depend on the reactant path taken.\nc. the enthalpy of a reaction depends on the pathway the reactants followed.\nd. the entropy of a reaction is the sum of the enthalpies of intermediate steps.

Answer

Answer:

B. The enthalpy of a reaction does not depend on the reactant path taken.

Brief Explanations:

Hess's law states that the total enthalpy change for a chemical reaction is independent of the sequence of steps (reaction pathway) used to go from reactants to products; it only depends on the initial and final states of the system. Options A refers to Gibbs free energy definition, C contradicts Hess's law, and D incorrectly links entropy to enthalpies of intermediate steps.
