If a mixture containing 3 moles of hydrogen and 1 mole of nitrogen is converted completely into ammonia, the ratio of volumes of reactants and products at the same temperature and pressure would be

Solution:

3H2 + N2 → 2NH3
∴ 3V 1V → 2V
Total initial volume = 3V + 1V = 4V
Final volume = 2V
Hence, ratio of initial and final volume will be 2 : 1

QUESTION: 33

32 g of oxygen and 3.0 g of hydrogen are mixed and kept in a vessel at 760 mm pressure and 0°C. The total volume occupied by the mixture will be nearly

Solution:

Total volume of a mixture of gases is equal to the sum of the partial volume of the constituent gases.
V1 + V2 = Vtotal
while V1, that is, partial volume of a gas in a mixture is defined as the volume which the gas would occupy if it were present alone in a container at temperature T and pressure p of the mixture.
So, number of moles of O2 = 32/32 = 1 mole
number of moles of H2 = 3/2 = 1.5 moles

similarly,


V2 = 33.600 dm3
Hence the total volume occupied by the mixture = 56.000 dm3
