Detailed Solution

  • Heat of reaction: The heat of reaction is the difference between the sum of the enthalpies of a product and the sum of the enthalpies of reactants at a specific temperature and constant pressure

                      Heat of reaction = HP - HR 

  • The change in the system's internal energy is equal to the heat of reaction at constant volume

                   Heat of reaction at constant volume = ΔE
