The quantity that this rule concerns is the sum of internal energy and the product of pressure and volume, though that quantity, governed by this law, is better known for a change in value that is equal to TdS plus Vdp.
The Bordwell cycle extends this principle to a related quantity. The quantity that this rule concerns is the sum of internal energy and the product of pressure and volume, though that quantity, governed by this law, is better known for a change in value that is equal to TdS plus Vdp. This law may be used to calculate a compound's lattice energy via the Born-Haber cycle. For 10 points, identify this prediction, which relies on the fact that a certain thermodynamic quantity is a state function, and suggests that the change in enthalpy is independent of the path from reactants to products.
