Question

Write any two characteristics properties of chemisorption

Answer 1

Answer:

two characteristics properties of chemisorption

• In chemisorption, the gas molecules or atoms are held to the solid surface by chemical bonds which can be a covalent bond or Ionic bond in nature.
• Chemisorptions is not reversible in nature because a surface compound is formed due to chemical interaction between the gas molecule & solid surface.

Answer 2

Explanation:

The range of heat required for accumulation is high. It ranges between 40-500 kJ/mol.

The chemical bond acts as an attracting force between the adsorbent and adsorbate.

Chemisorption is not reversible.

This process requires high temperatures.

The molecules accumulated, form a monolayer.

High activation energy is required.
