WebJan 11, 2024 · Delta H = Delta U + P Delta V . During a chemical reaction, energy is either gained or released. Since enthalpy is a state function, the change in enthalpy during a chemical reaction only depends ... WebSo Hess's Law tells us that delta H of this reaction, the change in enthalpy of this reaction, is essentially going to be the sum of what it takes to decompose these guys, which is the minus heat of formations of these guys, plus what it takes to reform these guys over here. So we can just write it as delta H of formation for C plus delta H of ...
