In an effort to reduce carbon dioxide emissions from a combustion reaction, it is proposed that a stack gas be reacted with hydrogen via the Sabatier reaction: \mathrm{CO}_{2}+4 \mathrm{H}_{2}-\mathrm{CH}_{4}+2 \mathrm{H}_{2} \mathrm{O} The stack gas composed of 8% CO2, 11% H20, and 81% N2 (by moles)will be fed to the reactor with an excess amount of hydrogen. The fractional conversion of hydrogen is 0.86. Based solely on the composition of the stack gas, select all statementsthat are true. The reaction was a complete combustion O The fuel that reacted was a hydrocarbon The fuel was fed in excess Air was fed in excess A dry basis is given The reaction was an incomplete combustion O A wet basis is given The fuel that reacted contained nitrogen The fuel that reacted contained sufler
