Question 13

A closed vessel contains gases at equilibrium.

3A(g)⇌B(g)+C(g)3\text{A(g)} \rightleftharpoons \text{B(g)} + \text{C(g)}3A(g)⇌B(g)+C(g)

The pressure is increased at constant temperature. The equilibrium amounts of B and C increase.

Why are greater equilibrium amounts of B and C obtained when the pressure is increased?

[1]
A

High pressure stops the reverse reaction, so only B and C are formed

B

High pressure makes the amounts of A, B and C equal at equilibrium

C

High pressure favours the product side because it has fewer gas molecules

D

High pressure favours the product side because it has more different gases
