Question 2. A mixture of 1-butanol (1) + water (2) forms an azeotrope where x₁ = 0.807 and T = 335.15 K. Assuming the following relations apply for the activity coefficients: In y₂ = A(x₁)² In Y₁ = A(x₂)² Given: Psat = 8.703 kPa and Pat = 21.783 kPa (a) Derive an expression for G/RT as a function of A and x₁ (b) Determine the numerical value of the constant A (c) Using modified Raoult's law, determine the pressure at x = 0.807 and T = 335.15 K.
