Problem $88$

A gas consisting of $70$mol$\%$ cyclohexane $(C_6{H}_{12})$ and $30$mol$\%$ nitrogen is fed to a

reactor at a temperature of $150C$ and a rate of $150$kmo$\frac{l}{h}.$ In the reactor, cyclohexane

undergoes decomposition to benzene $(C_6{H}_6)$ and hydrogen. The reactor operates at a

temperature of $300C$ and achieves a $70\%$ conversion of the cyclohexane fed to it$.$ At

what rate is energy removed from or added to this reactor?
