Consider the following reaction at equilibrium: 2NH₃ (g) N₂ (g) + 3H₂ (g)
Le Châtelier's principle predicts that the moles of H₂ in the reaction container will increase with __________.

A) some removal of NH₃ from the reaction vessel (V and T constant)
B) a decrease in the total pressure (T constant)
C) addition of some N₂ to the reaction vessel (V and T constant)
D) a decrease in the total volume of the reaction vessel (T constant)
E) an increase in total pressure by the addition of helium gas (V and T constant)
