Question

What happens to the yield on application of high pressure in the Habefs synthesis of ammonia?

• A. Increases
• B. Decreases
• C. Unaffected
• D. Reaction stops

Answer 1

Answer: (A)

Increases

Answer 2

Haber's process of synthesis of ammonia $N_{2}+3H_{2}2NH_{3}$
Since the number of molecules of gaseous products are less than the number of molecules of gaseous reactants, thus according to Le-Chatelier's principle, high pressure favoun the forward reaction ie, more ammonia will be obtained.
