Using the y-x and T-y-x diagrams in Figures 4.3 and 4.4, determine the temperature, amounts, and compositions of the equilibrium vapor and liquid phases at 101 kPa for the following conditions with a 100-kmol mixture of nC6 (H) and nC8 (C).(a) ZH = 0.5, ? = V/F = 0.2(b) ZH = 0.4, yH = 0.6(c) ZH = 0.6, xc = 0.7(d) ZH = 0.5, ? = 0(e) ZH = 0.5, ? = 1.0(f) ZH = 0.5, T = 200?F
