In moles of an ideal gas A and (1-n)moles of an ideal gas B, each at 1 atm, are mixed at total constant pressure. what ratio of A to B in the mixture maximizes the decrease in the Gibbs free energy of the system? if decreases in the Gibbs free energy is delta G^M, to what value must the pressure be increased in order to increases the Gibbs free energy of the gas mixture by (delta G^M)/2?
