1.	Which of the following conditions would improve the yield of ammonia production from Bosch-Haber process?(a) High temperature, high pressure(b) High temperature, low pressure(c) Low temperature, low pressure(d) Low temperature, high pressureI have been asked this question during an online interview.This intriguing question comes from P-Block Elements topic in section P-Block Elements of Chemistry – Class 12
Answer» Correct OPTION is (d) Low temperature, high pressure To explain: Following the Le Chatelier’s PRINCIPLE, since the forward reaction is exothermic (i.e. N2 + 3H2 → 2NH3), low temperatures would increase the RATE of reaction in TURN producing more ammonia. In addition to this, since the total number of molecules on the product side lesser, high pressures will increase the rate of reaction.
