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 can follow these steps:

### Step 1: Understand the Concept of Adsorption
Adsorption is the process by which atoms, ions, or molecules from a gas, liquid, or dissolved solid adhere to a surface. There are two main types of adsorption: physical adsorption (physisorption) and chemical adsorption (chemisorption).

### Step 2: Analyze the Given Temperatures
The question states that nitrogen does not adsorb at room temperature but does adsorb at 83 K. This indicates that the temperature plays a crucial role in the adsorption process.
