Problem $23$

A mixture $($gas$)$ of methane $(C{H}_4)$ and carbon monoxide $(CO)$ is fed to an incinerator at

a rate of $800\frac{\text{k}\text{m}\text{o}\text{l}}{h}.$ The mixture contains methane at $75$mol$\%.$ The unit is also fed

with air $($oxygen at $21$mol$\%$ and nitrogen at $79$mol$\%)$ at $50\%$ excess. In the reactor,

which operates under steady state conditions, $80\%$ of the methane and $90\%$ of the

carbon monoxide fed are being destroyed via the following reactions:

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

$CO+0\mathrm{.}5O_{2}C{O}_2$

Find the molar composition and the molar flow rate of the stream exiting the reactor.
