Step 1

The reaction is $3 \mathrm{H}_{2}+\mathrm{N}_{2} \longrightarrow 2 \mathrm{NH}_{3}$. This means that three moles of hydrogen react with one mole of nitrogen to produce two moles of ammonia. Show more…

Key Concepts

Reaction Stoichiometry

Reaction stoichiometry involves the numerical relationships between reactants and products in a balanced chemical equation. It allows one to determine how the consumption of one species relates to the consumption or formation of another, based on the coefficients in the balanced equation. In this case, the coefficients indicate that for every 1 mole of nitrogen, 3 moles of hydrogen are consumed, and 2 moles of ammonia are produced.

Rate of Reaction

The rate of reaction quantifies how quickly reactants are consumed or products are formed over time. It is often expressed in terms of the change in concentration per unit time. When comparing reaction rates for different species, the stoichiometric coefficients are used to relate these changes; for example, the rate of disappearance of hydrogen is three times the rate of disappearance of nitrogen, and the rate of appearance of ammonia is twice the rate of disappearance of nitrogen.
