c. Simultaneously solving the equilibrium relationship with the mass balance equation (you may want to try Matlab to solve this or even goal seek). To determine the equilibrium relationship you can use the following equation for an ideal system where you assume that the relative volatility (AB) is constant for all temperatures. In this case the relative volatility does change slightly with temperature. So to determine an overall AB use the AB calculated at 140C. yA=ABXA/lI+(ABI)xAly=V/F(IV/F)x+V/Fz c.
