The formation of ammonia is promoted by the use of __(high/low) pressure.

Open in App

Solution

Four volumes of reactants produce two volumes of product, hence high pressure favours the formation of ammonia. The optimum pressure is found to be 200 to 900 atm. Practically, a pressure of about 250 atm is used.
