2 mol gaseous ethene (C₂H4) and 1 mol gaseous water are combined in a reactor and react to form ethanol (C₂H5OH) according to: C2H4 (g) + H₂O (g) = C2H5OH (g). At a temperature of 500 K the equilibrium constant Kp is 1.256 x 10-2 bar ¹. Assume that all reactants and products behave like perfect gases. (i) (ii) Calculate the equilibrium composition (in mol %) of the gas mixture at 500 K and a combined pressure of 1 bar. What pressure is required to obtain 10 mol % of ethanol in the product mixture?
