(a) for a temperature of 500 k, determine the equilibrium composition for this system for an initial equimolar mixture of trans-2-butene and ethylene. what assumptions did you make? what is the equilibrium conversion of ethylene for an initial equimolar mixture of trans-2-butene and ethylene? (b) for a temperature of 500 k, what is the equilibrium composition and conversion for a 10: 1 of ethylene: trans-2-butene? (c) for a temperature of 600 k, what is the equilibrium composition and conversion for a 1: 1 of ethylene: trans-2-butene?
