What is the effect of catalyst on the rate of reaction ?

Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Definition of Catalyst**: A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It achieves this by providing an alternative reaction pathway with a lower activation energy. 2. **Types of Catalysts**: - **Positive Catalyst**: This type of catalyst increases the rate of reaction. It lowers the activation energy required for the reaction to proceed. - **Negative Catalyst (Inhibitor)**: This type of catalyst decreases the rate of reaction. It raises the activation energy required for the reaction to occur. ...
