Toluene is produced from $n-$heptane by dehydrogenation over a $C{r}_2{O}_3$ catalyst:

$C_7{H}_{16}{C}_6{H}_{5}C{H}_3+4H_2$

The feed is heated from $65$ to $800oF$ in a heater. It is then fed to a catalytic reactor, which operates isothermally, and converts $15$mol$\%$ of the $n-$heptane to toluene. Its effluent is cooled to $65oF,$ and is fed to a flash separator.

Assuming that all of the units operate at atmospheric pressure, determine the species flow rate in every stream
