The reaction for the same would be given by:

$3C+2O2\rightarrow 2CO+CO2$

Now the number of moles of C are equal to:

$\frac{3}{12}=\frac{1}{4}$

The number of moles of Oxygen are:

$\frac{5}{32}$

So the limiting reagent is Oxygen.

And so the mole fraction of CO2 would be equal to:

$\frac{\frac{1}{2}}{\frac{1}{2}+\frac{1}{1}}=\frac{1}{3}$
