$C_{10}{H}_{22}$ is burned in air $(79$ mole $\%N_2$ and the balance $O_2).$ On a dry basis, the composition of the flue gas $($i$.$e$.,$ product stream$)$ is given below in mole fractions:

$\backslash$table$[[$Oxygen$,0\mathrm{.}0866],[$Nitrogen$,0\mathrm{.}8250],[C{O}_2,0\mathrm{.}0796],[CO,0\mathrm{.}0088]]$

If possible, determine the percent excess air fed to the reactor.

If not possible, state what additional information must be given to solve.
