What is the relationship between pressure and the adsorption of gas by a solid, as per Le-Chatelier’s principle?

Options

  1. AHigher pressure decreases adsorption.
  2. BHigher pressure increases adsorption.
  3. CPressure has no effect on adsorption.
  4. DAdsorption is independent of pressure changes.

Correct answer

B. Higher pressure increases adsorption.

Step-by-step solution

The paragraph states that more gas is adsorbed when pressure is increased (Le–Chateliers’s principle).
