2CO + O2 \(\underrightarrow{to}\) 2CO2 (1)
2H2 + O2 \(\underrightarrow{to}\) 2H2O (2)
\(n_{CO_2}=\dfrac{8,96}{22,4}=0,4\left(mol\right)\)
\(n_{O_2}=\dfrac{13,44}{22,4}=0,6\left(mol\right)\)
Theo PT1: \(n_{O_2}=\dfrac{1}{2}n_{CO_2}=\dfrac{1}{2}\times0,4=0,2\left(mol\right)\)
\(\Rightarrow n_{O_2}\left(2\right)=0,6-0,2=0,4\left(mol\right)\)
Theo PT2: \(n_{H_2}=2n_{O_2}=2\times0,4=0,8\left(mol\right)\)
\(\Rightarrow V_{H_2}=0,8\times22,4=17,92\left(l\right)\)
Theo PT1: \(n_{CO}=n_{CO_2}=0,4\left(mol\right)\)
\(\Rightarrow V_{CO}=0,4\times22,4=8,96\left(l\right)\)
\(\Rightarrow\%V_{CO}=\dfrac{8,96}{8,96+17,92}\times100\%=33,33\%\)
\(\%V_{H_2}=\dfrac{17,92}{8,96+17,92}\times100\%=66,67\%\)
\(n_{O_2}=\dfrac{13,44}{22,4}=0,6\left(mol\right)\)
\(n_{CO_2}=\dfrac{8,96}{22,4}=0,4\left(mol\right)\)
PTHH:
\(2CO+O_2\underrightarrow{t^o}2CO_2\uparrow\)
0,4mol.-->.0,2mol-->.0,4mol
\(\Rightarrow V_{CO}=0,4.22,4=8,96\left(l\right)\)
\(2H_2+O_2\underrightarrow{t^o}2H_2O\uparrow\)
0,8mol.....0,4mol....0,4mol
\(\Rightarrow V_{H_2}=0,8.22,4=17,92\left(l\right)\)
\(\Rightarrow\%V_{H_2}=\dfrac{17,92}{17,92+8,96}.100\%\approx66,67\%\)
\(\Rightarrow\%V_{CO}=100\%-66,67\%=33,33\%\)
2CO+O2 ---> 2CO2 (1)
2H2+O2--->2H2O (2)
\(n_{O_2}=\dfrac{13,44}{22,4}=0,6\left(mol\right)\)
\(n_{CO_2}=\dfrac{8,96}{22,4}=0,4\left(mol\right)\)
Theo (1) : \(n_{O_2\left(1\right)}=\dfrac{1}{2}n_{CO}=\dfrac{1}{2}n_{CO_2}=\dfrac{1}{2}.0,4=0,2\left(mol\right)\)
=> \(n_{CO}=n_{CO_2}=0,4\left(mol\right)\)
=> \(n_{O_2\left(2\right)}=0,6-0,2=0,4\left(mol\right)\)
Theo (2) : \(n_{H_2}=2n_{O_2\left(2\right)}=0,4.2=0,8\left(mol\right)\)
=> Σ \(n_{h^2}=0,2+0,8=1\left(mol\right)\)
=> \(\%V_{H_2}=\dfrac{0,8}{1}.100=80\%\)
=> \(\%V_{CO}=100-80=20\%\)
