Although, nitrogen does not adsorb on a surface at room temperature, it adsorbs on the surface at 83 K. Which one of the following statements is correct?

Options

A. At 83 K, there is formation of monomolecular layer
B. At 83 K, there is formation of multimolecular layers
C. At 83 K, nitrogen molecules are held by chemical bonds
D. At 83 K, nitrogen is adsorbed as atoms

Explanation

To solve the question regarding the adsorption of nitrogen at different temperatures, we will follow these steps:

### Step 1: Understand the Concept of Adsorption
Adsorption is the process where gas or liquid molecules adhere to the surface of a solid or liquid. It is important to distinguish between two types of adsorption: physisorption (physical adsorption) and chemisorption (chemical adsorption).

**Hint:** Remember that physisorption involves weak van der Waals forces, while chemisorption involves stronger chemical bonds.
