Question 21

In the industrial production of sulfuric acid, sulfur dioxide reacts with oxygen to form sulfur trioxide.

sulfur dioxide+oxygen⇌sulfur trioxide \text{sulfur dioxide} + \text{oxygen} \rightleftharpoons \text{sulfur trioxide} sulfur dioxide+oxygen⇌sulfur trioxide

The ⇌ \rightleftharpoons\,⇌ symbol in this equation indicates that the reaction can occur in both the forward and backward directions.

Give the term used to describe this type of reaction.
