Question

In the Haber process for the synthesis of ammonia, the use of catalyst:

• A. increases the amount of ammonia formed without changing the rate of formation
• B. increases the rate of formation and amount of ammonia formed
• C. increases the rate of formation of ammonia without changing the amount of ammonia formed
• D. increases the rate of formation but decreases the amount of ammonia formed

Answer 1

The correct option is C increases the rate of formation of ammonia without changing the amount of ammonia formed

The Haber process combines nitrogen from the air with hydrogen derive into ammonia. The reaction is reversible and the production of ammonia is exothermic.

In this process Iron is used as catalyst.

The catalyst is used to increase the rate of formation of ammonia without changing the amount of ammonia formed.

$N_2+3H_2\to 2N{H}_3$

So answer is C.
