Which of the following is correct concerning Hess's law?

A-The change of enthalpy of a reaction can be found be subtracting the enthalpy of the products from the enthalpy of the reactants.

B-The change in enthalpy can be found be subtracting the enthalpy of the reactants from the enthalpy of the products.

C-The change in enthalpy can be found by adding the enthalpies of the individual thermochemical reactions of a chemical reaction.

D-The change in enthalpy can be found by subtracting the enthalpies of the individual thermochemical reactions of a chemical reaction.

Respuesta :

I believe the correct answer would be that the change in enthalpy can be found by adding the enthalpies of the individual thermochemical reactions of a chemical reaction. In Hess' Law, enthalpy is independent of the mechanism of the reaction. The enthalpy should be the sum of all the changes in the reaction.
