Question 7

The reaction between sulfur dioxide and oxygen to produce sulfur trioxide is reversible and can reach a state of dynamic equilibrium.

2SO2(g)+O2(g)⇌2SO3(g) 2\text{SO}_2\text{(g)} + \text{O}_2\text{(g)} \rightleftharpoons 2\text{SO}_3\text{(g)} 2SO2​(g)+O2​(g)⇌2SO3​(g)

The forward reaction is exothermic (gives out heat).

Explain how the position of equilibrium changes if the temperature of the reaction mixture is increased.
