3. Compute the following question by using Matlab program; A vapor at the dew point and 350kPa containing a mole fraction of 0.25 benzene (1) and 0.75 toluene (2) and 120kmol total is brought into contact with 140kmol of a liquid at the boiling point containing a mole fraction of 0.30 benzene and 0.70 toluene. The two streams are contacted in a single stage, and the outlet streams leave in equilibrium with each other. Assume constant molar overflow, calculate the compositions of the exit streams. 3.
