Enthalpy is a state function which means the energy change between two states is independent of the path. Since equation 1 and 2 add to become equation 3, we can say: ΔH3 = ΔH1 + ΔH2. WebWhen the bonds in ATP are broken new bonds are being formed, for example if ATP is being hydrolyzed to ADP + Pi the pyrophosphate bond between the outer two phosphates is being broken by "adding" a water molecule. The new bonds are lower energy (more stable) than the pyrophosphate bond and so the net effect is a release of energy. cheap vacations all-inclusive jamaica
