Q2(B) = = The activity coefficients of a benzene (1)-cyclohexane (2) mixture at 40 °C, are given by RT Iny,= Axz?and RT In Y = Axz?. At 40°C benzene-cyclohexane forms an azeotrope containing 49.4 mol % benzene at a total pressure of 202.5 mm Hg. If the vapour pressures of pure benzene and pure cyclohexane at 40 °C are 182.6 mm and 183.5 mm Hg, respectively, calculate the total pressure for a liquid mixture containing 12.6 mol % (10) benzene at 40 °C. Q3(A) Ethanol is manufactured by catalytic vapour phase hydration of ethylene 1C,H(8) + H,0 (8) = C,H,OH (8) ]. The reactor operates at 400 K and 2 bar and the feed is a gas mixture of ethylene and steam in the mol ratio 1:3. The equilibrium constant at 400 K is 0.25. Estimate the composition of the equilibrium mixture. Assume ideal gas behavior. (15] Q3(B) Calculate the pressure required for 50% dissociation of nitrogen tetroxide [NZO, (g) = 2 NO2 (s)) at 300 K. The standard heat of formation and Gibbs free energy of formation of the reactant and product species (298.15 K and 1 atm) are given below: (10) Ahro (kJ/mol) N204 (g) Ago (kl/mol) 9.33 NO2 (g) 97.947 33.304 51.295
