A gas mixture at 580.0°C and 113 kPa absolute enters a heat exchanger at a rate of 80.0 m3/hr. The gas leaves the heat exchanger at 150.0°C. The change in enthalpy of the gas during the cooling process is -7.00 kJ/mol. What is the heat required in kW? Assume the gas behaves ideally and that the changes in kinetic and potential energy are negligible.
