\(n_{CO}=\dfrac{11,2}{22,4}=0,5\left(mol\right)\\ 2CO+O_2\rightarrow\left(t^o\right)2CO_2\\ n_{O_2}=\dfrac{n_{CO}}{2}=\dfrac{0,5}{2}=0,25\left(mol\right)\\ \Rightarrow V_{O_2\left(đktc\right)}=0,25.22,4=5,6\left(l\right)\\ Vì:V_{O_2}=\dfrac{1}{5}.V_{kk}\\ \Leftrightarrow V_{kk}=5.V_{O_2}=5.5,6=28\left(l\right)\)
\(n_{CO}=\dfrac{11,2}{22,4}=0,5mol\)
\(2CO+O_2\underrightarrow{t^o}2CO_2\)
0,5 0,25
\(V_{O_2}=0,25\cdot22,4=5,6l\)
\(\Rightarrow V_{kk}=5V_{O_2}=5\cdot5,6=28l\)
