A binary liquid mixture is in equilibrium with its vapor at a temperature T=300 K. The liquid mole fraction x1 of species 1 is 0.4 and the molar excess Gibbs free energy is 200 J/mol. The value of the universal gas constant is 8.314 J/mol-K and γi denotes the liquid-phase activity coefficient of species i. If ln(γ1)=0.09, then the value of ln(γ2) up to 2 digits after the decimal point, is
Correct : 0.24
