Question

Define free energy and derive gibbs helmholtzequation

Answer 1

$<u>The equation is: where H is the enthalpy, T the absolute temperature and G the Gibbs free energy of the system, all at constant pressure p. The equation states that the change in the G/T ratio at constant pressure as a result of an infinitesimally small change in temperature is a factor H/T2.$

Answer 2

Gibs free energy is referred to the amount of useful energy left in a system which can be utilized.
