Aliquid stream at 25°c, containing 0.4 mol benzene/mol and the remaining toluene, is fed into an evaporator at a rate of 100 mol/s. the liquid and vapor stream (in equilibrium) are leaving the evaporator at 100°c and 1 atm (a) draw and label a flowchart (2 marks). (b) calculate the molar flow rate of the product streams and their compositions (6 marks). (c) prepare an inlet-outlet enthalpy table (6 marks). (d) calculate the amount of heat supplied or withdrawn. specified whether heat is supplied or withdrawn
