Question

In Haber's process, once the equilibrium is established, addition of nitrogen decreases the yield of ammonia.

• A. True
• B. False

Answer 1

The correct option is B False

In Haber's process, once the equilibrium is established, addition of nitrogen increases the yield of ammonia.
$N_2+3H_2\rightleftharpoons 2N{H}_3$
When nitrogen is added, the equilibrium will shift in the forward direction so that more and more of nitrogen reacts with hydrogen to form ammonia. This will nullify the effect of increase in the concentration of nitrogen.
