3. In a binary thermodynamic system of components A and B,xA=0.1. In the temperature range not much different from T=25C, the relative activity coefficients of the components are given by the empirical formulae lnA=935.111xAT3/2andA=0.003.lngamma(b)0.003 Calculate the molar excess quantities of entropy, enthalpy, and Gibbs potential of the system at 25C
