Which of the following is a wrong statement for physisorption?

Options

A. It is a reversible reaction
B. Reaction requires an energy of activation
C. The value of adsorption enthalpy is low
D. It generally occurs at low temperature

Explanation

To determine which statement about physisorption is incorrect, let's analyze each option step by step.

### Step 1: Understand Physisorption
Physisorption is the process where adsorbate molecules adhere to the surface of an adsorbent through weak van der Waals forces. This type of adsorption is characterized by several key features:
- It is generally a reversible process.
- It occurs at low temperatures.
- The adsorption enthalpy is low.
- No activation energy is required for the process.
