Question

Assertion (A): For the manufacture of ammonia by Haber’s process, low temperature is favourable.

Reason (R): The reaction of Haber’s process is endothermic.

पर्याय

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

• If both A and R are true, but R is not the correct explanation of A.

• If A is true, but R is false.

• If both A and R are false.

Answer 1

If A is true, but R is false.

Explanation:

According to Le Chatelier’s principle, a low temperature favours the forward reaction in the Haber process because the synthesis of ammonia from nitrogen and hydrogen is a highly exothermic reaction (releases heat), not endothermic. Therefore, the assertion is scientifically true, but the reason given is entirely false.
