Expert Solution

in this question, Gibbs free energy is given but at equilibria, it should be zero...so may be by mistake it has written ...so I corrected that question ... I have taken that as a standard Gibbs free energy and then I was able to calculate the solve the question... I hope this will help u ..thank u
