Question
Consider the following reaction at equilibrium:
2NH3(g) ? N2(g) + 3H2(g)
Le Chatelier'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)
Explanation / Answer
answer is B
as pressure decreases reaction will move to product side generating more moles and more pressure
