In a continuous steady$-$state combustion reactor,

methane and air are burned to produce a mixture of

carbon monoxide, carbon dioxide, and water. There

are $12$ mole$\%CH4,25\%O2,$ and $63\%N2$ in the

reactor's feed. Methane conversion is $80\%,$ and the

gas exiting the reactor has $4$moldCO$\frac{2}{m}$olCO in it$.$

Kindly record the responses, create a flowchart, and

write everything down on it$.$ Conduct a process

degree$-$of$-$freedom analysis. The product stream's

molar composition should then be determined.
