Options

  1. AIt diffuses into the bulk of the catalyst
  2. BIt reacts with the inner part of the bulk
  3. CIts molecules are held up due to loose chemical combination
  4. DIt remains unchanged in mass and composition

Correct answer

C. Its molecules are held up due to loose chemical combination

Step-by-step solution

The paragraph states that when a gas comes in contact with the surface of the catalyst, its molecules are held up there due to loose chemical combination.
