A mixture of fuel containing $40\%molC{H}_4,30\%mol{C}_2{H}_6,$ and $30\%mol{C}_4{H}_{10}$ initially at $300\mathrm{.}15K$ was burned in a furnace with $50\%$ excess air initially at $323\mathrm{.}15K,$ at a pressure of $760mmHg,$ and with $80\%RH.$ The fractional conversions of $C{H}_4,C_2{H}_6,$ and $C_4{H}_{10}$ were $0\mathrm{.}95,0\mathrm{.}90,$ and $0\mathrm{.}85,$ respectively. Of the fuel burned, $90\%$ of the total carbon content of the fuel was converted to $C{O}_2$ and the balance to $CO$ while $95\%$ of the total hydrogen $)$ content of the fuel was converted to water and the balance exited as $H_2$ gas. Starting with a basis of $100$ moles of the fuel mixture,
