Question

Assertion (A): Ammonia is recovered by liquification process in Haber’s process.

Reason (R): Nitrogen and hydrogen liquify with difficulty as compared to ammonia.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Options

• (1)

• (2)

• (3)

• (4)

Answer 1

(1)

Explanation:

In Haber’s process, the ammonia formed is recovered by cooling and liquefaction. Ammonia liquefies more easily than the unreacted nitrogen and hydrogen. Therefore, the Assertion (A) is true.

Nitrogen and hydrogen are more difficult to liquefy than ammonia under the conditions used. Therefore, the Reason (R) is true and correctly explains the Assertion.

Hence, both A and R are true, and R is the correct explanation of A.
