A gas mixture at 595.0C and 119kPa absolute enters a heat exchanger at a rate of 64.0m3/h. The gas leaves the heat exchanger at 290.0C. The change in enthalpy of the gas during the cooling process is 5.00kJ/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
