Problem $4$

A synthetic gas generated from coal has the following composition: $C{O}_2,7\mathrm{.}2\%$; $CO,24\mathrm{.}3\%$;$H_2,14\mathrm{.}1\%$;$C{H}_4,3\mathrm{.}5\%$;$N_2,50\mathrm{.}9\%.$

a$)$ Calculate the cubic feet of air necessary for complete combustion per cubic foot of synthetic gas at $750F$ and $738mmHg.$

b$)$ If $38\%$ excess air were used for combustion, what volume of flue gas would be produced per cubic foot of synthetic gas at standard conditions?

c$)$ Calculate the flue gas composition for $($a$)$ and $($b$).$

d$)$ Determine the ratio of the partial pressures of $CO$ and $C{O}_2.$
