Benzene is heated from 300 K (liquid) to 450K (superheated vapor) at a constant pressure of 3 bar at a rate of 100 kmol/hr in a heat exchanger. (Tsat = 392K at 3 bar) A) Calculate the heat exchanger duty in kW, B) What is the latent heat of vaporization Tsat in kJ/mol? (Answers are 1366 kW and 28.4 kJ/mol) Please show work for good rating.
