Answer
Both A and R are true and R is the correct explanation of A.
Explanation — Ammonia obtained from Haber's process is separated from the unreacted nitrogen and hydrogen by liquification process. Hence, the assertion (A) is true.
Ammonia is recovered by liquification process because ammonia is liquified easily as compared to Nitrogen and Hydrogen. Hence, the reason (R) is true and it is the correct explanation of assertion (A).
