Recently got this question on a test.

N2(g) + 3H2(g) <-> 2NH3(g)
dH(rxn)= -91.8 kJ/mol (So reaction is exothermic)

In order to maintain the maximum yield of ammonia when raising the temperature of the reaction, scientists should:

A. Maintain N2 and H2 at high pressure
B. Continuously remove the excess heat produced by the forward reaction

From the looks of it, both answer choices A and B seem like it would shift the reaction to the right to increase the yield of ammonia. The answer was A. Any ideas?

They both seem right to me
