Ammonia is manufactured in large amounts by the reaction N2(g) + 3H2(g) -> 2 NH3

Question

Ammonia is manufactured in large amounts by the reaction N2(g) + 3H2(g) -> 2 NH3(g)

a) How is the rate of consumption of H2 related to the rate ofconsumption of N2?

b) How is the rate of formation of NH3 related to the rate ofconsumption of N2?

Thanks in advance.

Explanation / Answer

Ammonia is manufactured in large amounts by the reaction N2(g) + 3H2(g) -> 2 NH3(g) here 1 mole of nitrogen reacts with 3 moles of hydrogen toform 2 moles of ammonia so rate of consumption of hydrogen =(-H2/t) so rate of consumption of nitrogen =(-N2/t) and rate of formation of ammonia = NH3g / t so we know that from this reaction , (1/3)(-H2/t) =(-N2/t) = (1/2)(NH3g / t) so the answers are: a) How is the rate of consumption of H2 related to the rate ofconsumption of N2? (1/3)(-H2/t) =(-N2/t) b) How is the rate of formation of NH3 related to the rate ofconsumption of N2? (-N2/t) = (1/2)(NH3g / t)
