This quantity remains constant in the Joule-Thomson effect. It equals internal energy plus the product of pressure and volume. The Gibbs Free Energy is given by this quantity minus the product of temp
This quantity remains constant in the Joule-Thomson effect. It equals internal energy plus the product of pressure and volume. The Gibbs Free Energy is given by this quantity minus the product of temperature and entropy. For a multi-step reaction, it can be calculated independently of the pathway and is equal to the sum of its changes in each step according to (*) Hess's Law. It is positive for an endothermic reaction. For 10 points, name this "heat content" of a thermodynamic system, symbolized capital H.
