Generally high temperature is favourable for chemisorption . ' Why ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Chemisorption**: Chemisorption is a type of adsorption where a chemical bond is formed between the adsorbate (the substance being adsorbed) and the adsorbent (the surface on which adsorption occurs). This process is similar to a chemical reaction.

2. **Effect of Temperature on Reaction Rates**: In general, increasing the temperature of a system increases the kinetic energy of the molecules involved. This results in more frequent and energetic collisions between the adsorbate and adsorbent molecules.

3. **Initial Increase in Chemisorption**: As the temperature rises, the rate of chemisorption initially increases. This is because the increased kinetic energy leads to more effective collisions, which can overcome the activation energy barrier for bond formation between the adsorbate and adsorbent.
