After the reactio is over between adsorbed reactants, it is important to create space for the other reactant molecules to approach the surface and react. The process responsible for this is known as

Options

A. sorption
B. desorption
C. physisorption
D. chemisorption

Explanation

To solve the question, we need to identify the process that occurs after the reaction between adsorbed reactants, which allows space for other reactant molecules to approach the surface and react.

### Step-by-Step Solution:

1. **Understanding Adsorption and Reaction**:
- Adsorption is the process where molecules adhere to the surface of a solid or liquid (adsorbent).
- When reactants are adsorbed onto a surface, they can react to form products.

2. **Identifying the Need for Space**:
- After the reaction between the adsorbed reactants is complete, the products formed need to be removed from the surface to allow new reactant molecules to adsorb and react.

3. **Defining the Process**:
- The process that allows the products to detach from the surface is crucial for continuous reactions. This process is known as desorption.

4. **Contrasting with Adsorption**:
- Desorption is the reverse of adsorption. While adsorption involves the attachment of molecules to a surface, desorption involves the release of those molecules from the surface.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the process responsible for creating space for other reactant molecules after the reaction is known as **desorption**.

### Final Answer:
The process responsible for creating space for other reactant molecules to approach the surface and react is known as **desorption**.
