Correct Answer: Option A
Explanation:
Low temperatures favour ammonia formation because the reaction is exothermic, but the reaction becomes too slow. Very high temperatures increase reaction speed but reduce ammonia yield. Therefore, a moderate temperature is used to balance yield and reaction speed.
