Question $4)80\%$ conversion of substance A is achieved with the A$+$B$->$C$+$D reaction. Substances A and B are fed into the reactor at $310$ K and at a flow rate of $2$ mol$/$second and $3$ mol$/$second$,$ respectively. Specific heats $($in J$/$mol K$)$ are given as $200,150,220$ and $180$ for substances A$,$ B$,$ C and D$,$ respectively. The reactor contains a jacket through which water passes at an average temperature of $293$ K$.$ The total heat transfer coefficient is given as $300$ J$/($m$^2.$sec$.$K$),$ and the heat transfer area is given as $0\mathrm{.}75$ m$^2.$ The reaction heat is given as $>30000$ J$/$mol A at $300$ K$.$ What is the temperature in K at steady state in the reactor?
