a) \(n_{PbO}=\dfrac{22,3}{223}=0,1\left(mol\right)\)
\(n_{ZnO}=\dfrac{32,4}{81}=0,4\left(mol\right)\)
PTHH: PbO + H2 --to--> Pb + H2O
0,1-->0,1
ZnO + H2 --to--> Zn + H2O
0,4-->0,4
=> VH2 = (0,1 + 0,4).22,4 = 11,2 (l)
b)
\(n_{Fe_3O_4}=\dfrac{58}{232}=0,25\left(mol\right)\)
PTHH: Fe3O4 + 4CO --to--> 3Fe + 4CO2
0,25--->1
=> VCO = 1.22,4 = 22,4 (l)
nPbO=\(\dfrac{22,3}{223}\)=0,1(mol)
nZnO=\(\dfrac{32,4}{81}\)=0,4(mol)
nH2=0,1+0,4=0,5(mol)
VH2=0,5.22,4=11,2(l)
nFe3O4=\(\dfrac{58}{232}\)=0,25(mol
VCO=1.22,4=2,24l
