a) PTHH
4CO + Fe3O4 \(\rightarrow\) 3Fe + 4CO2 (1)
3H2 + Fe2O3\(\rightarrow\) 2Fe + 3H2O (2)
b) Theo PT (1)=> nCO = 4 . nFe3O4 = 4 x 0.1 = 0.4(mol)
=> VCO = n x 22.4 = 0.4 x 22.4 =8.96(l)
Theo PT(2) => nH2 = 3 . nFe2O3 = 3 x 0.1 = 0.3(mol)
=> VH2 = n x 22.4 = 0.3 x 22.4 =6.72(l)
c)Theo PT(1) => nFe = 3. nFe3O4 = 3 x 0.1 = 0.3(mol)
=> mFe(PT1) = n .M = 0.3 x 56 =16.8(g)
Theo PT(2) => nFe = 2 x nFe2O3 = 2 x 0.1 = 0.2(mol)
=> mFe(PT2) = n .M = 0.2 x 56=11.2(g)
