| This binding affinity is related to free enthalpy of the formation of the product of metal and ligand. |
| The internal energy of a system, like the enthalpy, is a state property, so it is fixed when the state of the system is specified. |
| The change in heat content of the products relative to the reactants in a chemical reaction is known as the change in enthalpy. |
| Greater energy savings and maintained comfort are achieved with enthalpy economizers, though they cost more to install and maintain. |
| Despite the large increase in enthalpy and entropy, the free energy difference between the closed and open conformations is relatively small. |
| So, we can get useful work out of a system by reducing enthalpy or by increasing entropy. |
