\(n_C=\dfrac{3,6}{12}=0,3\left(mol\right)\)
\(n_{O_2}=\dfrac{4,48}{22,4}=0,2\left(mol\right)\)
PTHH: C + O2 -to-> CO2
_____0,2<--0,2------>0,2_____(mol)
C + CO2 -to-> 2CO
0,1->0,1-------->0,2_________(mol)
=> \(\left\{{}\begin{matrix}n_{CO_2}=0,2-0,1=0,1\left(mol\right)\\n_{CO}=0,2\left(mol\right)\end{matrix}\right.\)
=> \(\left\{{}\begin{matrix}\%V_{CO_2}=\dfrac{0,1}{0,1+0,2}.100\%=33,33\%\\\%V_{CO}=\dfrac{0,2}{0,1+0,2}.100\%=66,67\%\end{matrix}\right.\)
