Question

For which of the following is the adsorption theory applicable?

• A. Homogeneous catalysis
• B. Heterogeneous catalysis
• C. Auto catalysis
• D. Induced catalysis

Hint:

Adsorption theory is particularly important in heterogeneous catalysis, where the catalyst adsorbs the reactants on its surface.

Answer 1

The Correct Option is B

Step 1: Understanding adsorption theory.
The adsorption theory explains the process where reactant molecules are adsorbed on the surface of a solid catalyst. This theory is primarily applicable in heterogeneous catalysis, where the catalyst is in a different phase from the reactants.
Step 2: Analyzing the options.
(1) Homogeneous catalysis: This involves catalysts and reactants in the same phase and does not follow the adsorption theory.
(2) Heterogeneous catalysis: The adsorption theory is specifically applicable here, as the catalyst is in a different phase (usually solid) and the reactants are adsorbed onto its surface.
(3) Auto catalysis: This is when a product of the reaction catalyzes its own formation. Adsorption theory does not apply in this case.
(4) Induced catalysis: This involves a catalyst being activated by the reactants, not necessarily involving adsorption.
Step 3: Conclusion.
The correct answer is (2) Heterogeneous catalysis.
