12) Most nitrogen exists in a gaseous state. Plants require a soluble form of nitrogen so they can absorb it from the ground. Ammonia is a good fertilizer, as the mass
percent of nitrogen in ammonia is very high. The following reaction is used to
convert gaseous nitrogen into ammonia, which can be used as fertilizer.
N2(g) + 3 H2(g) → 2 NH;
Suppose 186.3 g of N2(g) react with 289.8 g of H2(g).
a. Which reactant is limiting? Justify your answer.
b. What mass of ammonia can be produced in theory?
c. If this reaction is know to have a 73.8% yield, what mass of ammonia
could you expect to produce?
