Question

In a chemical reaction, the reactants combine to form the final product. Before making the final product, they form an intermediate complex: C + D -> C – D -> E The reactants C and D form intermediate molecule C – D and then molecule E. The enthalpy change of reaction does not depend on the

A. State of reactants and products.

B. Nature of reactants and products.

C. Nature of the intermediate molecule.

D. Nature of C, D, and E.

E. Initial and final enthalpies of the reaction

Answer 1

Because enthalpy is a state function, the magnitude of ΔH depends on only the initial and final states of the system, not on the path taken, so intermediates don't affect it.
