Download Solution PDFExplanation:
There are eight properties of a system, namely pressure (p), Volume (V), temperature (T), internal energy (u), enthalpy (h), entropy (s), Helmholtz function (f) and Gibbs function (g) and h, f and g are referred to as thermodynamic potentials.
Helmholtz function f = u - Ts
Gibbs free function g = h - Ts
Gibbs free energy function (G)
G = H – TS
G = f(H, T, S)
Gibbs free energy functions is a property comprises enthalpy, temperature, and entropy.
Gibbs free energy is a measure of the amount of energy available to do work in an isothermal and isobaric (constant temperature and pressure) thermodynamic system.
