Question

The purpose of liquefying the ammonia produced in the Haber’s process to separate hydrogen from uncombined nitrogen and hydrogen.

• A. To separate ammonia from uncombined nitrogen and hydrogen.
• B. To separate hydrogen from uncombined nitrogen and hydrogen.

Answer 1

The correct option is B

To separate hydrogen from uncombined nitrogen and hydrogen.

In Haber's process, after each cycle, the temperature of the gases is lowered. When this is done, the pressure increases and liquefies the ammonia, while hydrogen and nitrogen remain in the gaseous state. The liquid ammonia can be separated from this mixture.

Hence the ammonia produced in the Haber’s process is liquefied to separate ammonia from uncombined nitrogen and hydrogen.
