A gas mixture at 485.0 °C and 123 kPa absolute enters a heat exchanger at a rate of 79.0 m³/h. The gas leaves the heat exchanger at 300.0 °C. The change in enthalpy of the gas during the cooling process is -4.80 kJ/mol. What is the heat required, in kilowatts? Assume the gas behaves ideally and that the changes in kinetic and potential energy are negligible. heat required: kW
