2) 2SO 2 + 1O 2 + 2H 2 O à 2H 2 SO 4

a. If 12.5 mols of SO 2 react, how many moles of H 2 SO 4 will be produced?

b. If 20 moles of H 2 O are used, how many moles of oxygen would be used?

Balanced reaction: 2 SO2 + O2 + 2 H2O → 2 H2SO4

a) From the coefficients, SO2 : H2SO4 = 2 : 2 = 1 : 1, so 12.5 mol SO2 → 12.5 mol H2SO4.

b) H2O : O2 = 2 : 1, so mol O2 = 20 mol H2O × (1/2) = 10 mol O2.
