Ethylene oxide is produced by oxidation of ethylene and side reaction occurs:

$C_2{H}_4+\frac{1}{2}{O}_2{C}_2{H}_{4}O$

$C_2{H}_4+3O_{2}2C{O}_2+2H_{2}O$

Ethylene enters the reactor at a rate of $100mo\frac{l}{m}in$ at $200C$ and oxygen enters at a rate of $200mo\frac{l}{m}in$ at $200C.$ The reactions are performed at $500C$ and the product leaves at $500C.$ An ethylene conversion of $85\%$ is achieved and the yield of ethylene oxide is $0\mathrm{.}6.$ Calculate the heating or cooling requirement in $kW.$
