The given reaction is a gas-evolution reaction. If the reaction is allowed to proceed with the volume of the container is kept constant,
Nitrogen and hydrogen react to form ammonia according to the following equation:
N2(g) + 3 H2(g) → 2 NH3(g)
Consider the following representations of the initial mixture of reactants and the resulting mixture after the reaction has been allowed to react for some time:
If the volume is kept constant, and nothing is added to the reaction mixture, what happens to the total pressure during the course of the reaction?
