Question

Write the relation between Gibbs free energy and net work done by the system​

Answer 1

Answer:

ΔG = ΔH - TΔS

Explanation:

Gibbs free energy measures the useful work obtainable from a thermodynamic system at a constant temperature and pressure.

When a system changes from an initial state to a final state, the Gibbs free energy (ΔG) equals the work exchanged by the system with its surroundings, minus the work of the pressure force. Gibbs energy (also referred to as ∆G) is also the chemical potential that is minimized when a system reaches equilibrium at constant pressure and temperature. As such, it is a convenient criterion of spontaneity for processes with constant pressure and temperature. Therefore, Gibbs free energy is most useful for thermochemical processes at constant temperature and pressure.
