The graph for the reaction N 2 g + 3 H 2 g ⇌ 2 NH 3 g is given below. Identify and write reactions C and D .

N 2 g + 3 H 2 g ⇌ 2 NH 3 g is reversible reaction. Reaction C represents forward reaction. It is represented as follows, N 2 g + 3 H 2 g → 2 NH 3 g Reaction D represents backward reaction. It is represented as follows, 2 NH 3 g → N 2 g + 3 H 2 g

The graph for the reaction N 2 g + 3 H 2 g ⇌ 2 NH 3 g is given below. What happens to the position of point A in the graph when a catalyst is used? Redraw the graph.

Catalyst used in the reaction helps to attain equilibrium quickly. The new equilibrium is represented as follows, Catalysts are the substances which increase the rate of reactions without itself undergoing any permanent chemical change. In reversible reaction, catalyst increases the rate of both forward and backward reaction to the same extent. As a result the system reaches equilibrium at a faster rate. Once equilibrium has been reached, the rate of chemical can be controlled by altering other factors.
