a) PTHH: \(4P+5O_2-^{t^o}\rightarrow2P_2O_5\)(1)
\(S+O_2-^{t^o}\rightarrow SO_2\)(2)
b) \(TheoPT\left(1\right):n_{O_2}=\frac{5}{4}n_P=\frac{5}{4}.\frac{3,1}{31}=0,125\left(mol\right)\)
\(TheoPT\left(2\right):n_{O_2}=4n_S=\frac{6,4}{32}=0,2\left(mol\right)\)
\(\sum n_{O_2}=0,125+0,2=0,325\left(mol\right)\)
\(\Rightarrow V_{O_2}=0,325.22,4=7,28\left(l\right)\)
a)\(4P+5O2-->2P2O5\)
\(S+O2--->SO2\)
b)\(n_P=\frac{3,1}{31}=0,1\left(mol\right)\)
\(n_S=\frac{6,4}{32}=0,2\left(mol\right)\)
\(n_{O2}=\frac{5}{4}n_P=0,125\left(mol\right)\)
\(n_{O2}=n_S=0,2\left(mol\right)\)
\(\sum n_{O2}=0,2+0,125=0,325\left(mol\right)\)
\(V_{O2}=0,325.22,4=7,28\left(l\right)\)
