7.51. Liquid benzene at 25°C and 1.2 bar is converted to vapor at 200°C and 5 bar in a two-step steady-flow process: vaporization in a counterflow heat exchanger at 1.2 bar, followed by compression as a gas to 5 bar. Determine the duty of the exchanger and the power requirement of the compressor in kJ mol-¹. Assume a compressor efficiency of 75%, and treat benzene vapor as an ideal gas with constant Cp 105 J-mol-1.K-1 =
