The process which is catalysed by one of the products is called

Options

A. auto catalysis
B. acid-base catalysis
C. negative catalysis
D. None of these

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term used to describe a process that is catalyzed by one of the products of the reaction.

2. **Identifying the Concept**: The process where one of the products acts as a catalyst is known as **autocatalysis**.

3. **Defining Autocatalysis**: In autocatalysis, the reaction involves reactants that produce products, and at least one of these products serves as a catalyst to speed up the reaction.

4. **Example of Autocatalysis**: Consider a hypothetical reaction:
\[ A + B \rightarrow C + D \]
Here, either product C or D can act as a catalyst. For instance, if D is the product that acts as a catalyst, it will enhance the rate of the reaction without being consumed in the process.

5. **Conclusion**: Therefore, the answer to the question is that the process which is catalyzed by one of the products is called **autocatalysis**.
