Question 67

Nitrosyl chloride decomposes in a reversible reaction.

2NOCl(g)⇌2NO(g)+Cl2(g) \mathrm{2NOCl(g) \rightleftharpoons 2NO(g) + Cl_{2}(g)} 2NOCl(g)⇌2NO(g)+Cl2​(g)

The reaction mixture is at equilibrium in a closed container. The pressure is increased while the temperature remains constant.

Explain how increasing the pressure affects the position of equilibrium.
