State the type of chemical reactions, represented by the following equations :
PQ+RS`to` PS+RQ

Explanation

To determine the type of chemical reaction represented by the equation \( PQ + RS \rightarrow PS + RQ \), we can analyze the components involved in the reaction.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- The reactants are \( PQ \) and \( RS \).
- The products are \( PS \) and \( RQ \).
