the temperature is increased, the position of equilibrium moves to the left, and the yield of ammonia decreases.

i don't rlly get the question but this is what i found on the internet :/

Explanation:

When the temperature is increased, the position of equilibrium moves in the endothermic direction to reduce the temperature. ... This means that as the temperature is increased, the position of equilibrium moves to the left, and the yield of ammonia decreases.

give me abc and i will get it for u.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
