Action of catalyst depends on

  1. A
    mass
  2. B
    solubility
  3. C
    particle size and surface area
  4. D
    None of the above

Solution & Step-by-step Explanation

The efficiency and chemical action of a solid heterogeneous catalyst are highly dependent on its active surface area. Decreasing the particle size significantly expands the effective surface area available for reactant adsorption, directly altering the rate of reaction.
