The use of Hess’s Law to determine enthalpy change for a compound from the values of heat of combustion is to be explained. Concept introduction: Hess’s Law states that the change in enthalpy fora chemical reaction remains same whether the reaction takes place in a single step or in a number of steps. The enthalpy change for a reaction is a state function. It depends upon the initial and final states of the system and not on the path followed.
