Determine concentration for methane $(C{H}_4)$ and $CO$ in the final products for the

following reaction in a gas flow PFR system: $3C{H}_4+4O_{2}C{O}_2+2CO+6H_{2}O(g)$

$30\%$ methane is mixed with $70\%$ air before entering the reactor. Limiting reactant conversion is

$50\%.$ The reactor volume is $267$ liter The system is

operated at constant temperature $(400K).$ The initial pressure is latm. The pressure drop

parameter ${}_p=0\mathrm{.}0005L^{-1}.$ Assume gas is ideal gas.
