One hundred kmol per hour of subcooled liquid at 300 K and 3 bar is superheated to 500 K in a steady-How heat exchanger. Estimate the exchanger duty (in kW) for one
of the following:

(a) Methanol, for which Tsat = 368.0 K at 3 bar.

(b) Benzene, for which Tsat = 392.3 K at 3 bar.

(c) Toluene, for which Tsat = 426.9 K at 3 bar.
