Solution: An initial mixture of nitrogen gas and hydrogen gas is reacted in a rigid container at a certain temperature by the reaction3H2(g) + N2(g) ⇌ 2NH3(g)At equilibrium, the concentrations are [H 2] = 5.0 M

Problem

An initial mixture of nitrogen gas and hydrogen gas is reacted in a rigid container at a certain temperature by the reaction

3H2(g) + N2(g) ⇌ 2NH3(g)

At equilibrium, the concentrations are [H 2] = 5.0 M, [N 2] = 8.0 M, and [NH3] = 4.0 M. What were the concentrations of nitrogen gas and hydrogen gas that were reacted initially?
