The enthalpy change of the reaction is to be calculated. Concept introduction: The change in the enthalpy of a reaction when reactants are converted to products is the same, whether the reaction takes place in one step or in many steps. This law is known as Hess’s law. On adding the thermochemical equations, the enthalpy change value is also added, which gives the enthalpy change of the net reaction. On reversing any equation, the sign of enthalpy change value is changed to the opposite sign.
