Ammonia decomposes completely to hydrogen and nitrogen gas. If the total pressure of the reaction vessel at the end of the reaction is 250 mm Hg, what is the partial pressure of nitrogen gas?
Solution:
Consider the decomposition reaction of ammonia into hydrogen and nitrogen gas as follows
Basis: 2 moles NH3 = 3 moles H2 = 1 mole N2
If the total pressure of the reaction vessel at the end of the reaction is 250 mm Hg, therefore, by Dalton's Law of Partial Pressure, the partial pressure of nitrogen gas is
