Start from the Boltzmann equation as given in picture a) Derive an equation to prove that the molar configurational entropy of mixing two different types of atoms (A and B) is only a function of their mole fractions b) Use this equation that you obtained to find the configurational entropy change when 30 gram moles of Ag are alloyed with 70 gram moles of Au.
