A binary liquid mixture consists of C2H4(1) and C3H6(2). If the liquid equilibrium composition x1=69.1mol%C2H4 at 492K, calculate NOTE: Assume that the mixture behaves like an ideal solution. The Antoine equation is of the form: ln(Psat[bar])=AT[K]+CB ANTOINE COEFFICIENTS: a) The vapor pressure of ethylene C2H4 b) The vapor pressure of propylene C3H6 c) The total pressure P d) The equilibrium composition of the vapor phase (1)
