The curve showing variation of x/m with temperature is inverted 'V' shape. What is the type of adsorption ?

Explanation

To determine the type of adsorption based on the given information about the curve showing the variation of \( \frac{x}{m} \) (amount of adsorption) with temperature, we can follow these steps:

### Step 1: Understand the Graph
The graph is described as having an inverted 'V' shape. This indicates that as temperature increases, the amount of adsorption initially increases and then decreases after reaching a certain temperature.

### Step 2: Analyze the Behavior of Adsorption
- **Initial Increase**: The initial increase in adsorption with temperature suggests that the adsorbate molecules are gaining energy, which allows them to overcome energy barriers and adhere to the surface more effectively.
- **Subsequent Decrease**: The decrease in adsorption after reaching a peak temperature indicates that at higher temperatures, the energy may be sufficient to desorb the adsorbate from the surface, leading to a reduction in the amount of adsorption.
