Liquid benzene at 25°C and 1.2 bar is converted to vapor at 200°C and 5 bar in a twostep steady-flow process: compression by a pump to 5 bar, followed by vaporization in a counterflow heat exchanger. Determine the power requirement of the pump and the duty of the exchanger in kJ⋅mol⁻¹. Assume a pump efficiency of 70%, and treat benzene vapor as an ideal gas with constant C_P = 105 J⋅mol⁻¹⋅K⁻¹.
