Answer:
A. Remove ammonia
Step-by-step explanation:
Hello,
In this case, for the given equilibrium reaction, it is possible to favor the direct reaction (rightwards) or the inverse reaction (leftwards) by applying the Le'Chatelier's principle which among others, states that in terms of addition or removal of a species, equilibrium could be shifted.
Thus, for this reaction, it is required to shift the reaction rightwards, for that reason, in terms of addition or removal of the involved species in the reaction we say that:
- Adding either nitrogen or hydrogen will shift the reaction rightwards as more ammonia is formed to reach equilibrium.
- Removing ammonia will shift the reaction rightwards as more hydrogen and nitrogen will produce more ammonia to attain equilibrium again.
For that reason, the feasible answer is: A. Remove ammonia
Best regards.
