U21A 2(A) In Y2 X2 In Y2 An ideal vapour-liquid mixture of n-hexane (1) and n-heptane (2) is under equilibrium conditions. Calculate the following: (a) vapour composition at 27 °C when the liquid phase contains 20 mol% n-hexane. (4] (b) liquid composition at 27 °C when the vapour phase contains 20 mol% n-hexane. [4] (c) vapour composition at a total pressure of 30 kPa and the liquid phase containing 20 mol% nhexane (show calculations for only one iteration). [7] The Antoine constants for n-hexane and n-heptane are given below: А B с n-hexane 13.8216 2697.55 224.37 n-heptane 13.8567 2911.32 216.64 In psat (kPa) = A B t(°C) + C
