    Sourav,this is gibbs free energy and in previous query there it is helmholtz free energy... The Gibbs' free energy is the energy available to do non-PV work in a thermodynamical...

    in helmholtz free energy you derive the relation by keeping volume constant....but here as gas expands and work of expansion is also there...volume is not constant
  • Priyanshu kumar thankyou
    Yes sourav,as in your previous query you see -delA=Wrev=Wmax

    Reversible process produce the maximum amount of work...So Wrev=Wmax

    Sourav here volume changes and work done by the gas on expansion against the external pressure
