Question

According to Hess's Law, what is the relationship between the standard reaction enthalpy of a reaction that occurs in several steps and the standard enthalpies of the intermediate reactions?, The standard reaction enthalpy is always greater than the sum of the standard enthalpies of the intermediate reactions., The standard reaction enthalpy is always equal to the sum of the standard enthalpies of the intermediate reactions., The standard reaction enthalpy is always less than the sum of the standard enthalpies of the intermediate reactions., The standard reaction enthalpy has no relationship with the standard enthalpies of the intermediate reactions.
