Ethyl chloride is manufactured by the reaction of Ethane and chlorine gases at $500C.$

$C_2{H}_6(g)+C{l}_2{C}_2{H}_{5}Cl(g)+HCl(g)$

$50\%$ excess chlorine is fed into the reactor at $120C,1$ bar and ethane is supplied at $250C$ at the

same pressure.

a$)$ Calculate the amount of heat that must be transferred from reactor.

b$)$ If you want to maintain the reactor temperature at $500C,$ how many kilograms per minute of

saturated steam at $10$ bar should be fed into cooling coil within the reactor to produce steam at

at $400C,10$ bar.

Heat capacity of ethyl chloride is given as; $Cp=20\mathrm{.}2{10}^{-3}+22\mathrm{.}92{10}^{-5}T-14\mathrm{.}1{10}^{-8}{T}^2,k\frac{J}{m}$ole$-{?}^{-0}C.$
