A gas mixture at ${410\mathrm{.}0}^{-}C$ and $125$kPa absolute enters a heat exchanger at a rate of $73\mathrm{.}0\frac{m^3}{h}.$ The gas leaves the heat exchanger

at $225\mathrm{.}0C.$ The change in enthalpy of the gas during the cooling process is $-2\mathrm{.}90k\frac{J}{m}ol.$

What is the heat required, in kilowatts? Assume the gas behaves ideally and that the changes in kinetic and potential energy

are negligible.
