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 counter flow 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  C_P = 105 J⋅mol⁻¹⋅K⁻¹.
