Having some troubles with this problem involving Cp^ig0.1 mol/s of carbon dioxide (CO2) enters a heat exchanger in steady flow at 221.5 bars and 650 K. It exits the heat exchanger at 350 K with negligible change in pressure. Determine the rate (J/s) at which heat must be removed from the CO2 in the heat exchanger:
(a) assuming CO2 behaves as an ideal gas.
(b) assuming CO2 follows the principle of corresponding states.
(c) assuming CO2 follows the van der Waals fluid.
