1- Methane is burned with atmospheric air. The analysis of the products on a dry basis is as follows: $\begin{array}{ll}?{\mathrm{CO}}_2& =10.00\%\\ ?\mathrm{CO}& =0.53\%\\ ?{\mathrm{O}}_2& =2.37\%\end{array}$ Calculate the equivalence ratio. 2- Determine the molal analysis of the products of combustion when octane ${\mathrm{C}}_8{\mathrm{H}}_{18}$ is burned with $200\%$ theoretical air. ?n: Determine the stoichiometric $A/F$ ratio.
