Question 7

Rates of Reaction

The efficiency of a solid catalyst to increase reaction rates depends on its

  1. A.surface area
  2. B.solubility
  3. C.concentration
  4. D.quantity
Show the answer and explanation

Answer: A (surface area)

Explanation

Reactions on a solid catalyst happen at its surface, so the larger the surface area (e.g. powder or fine mesh), the better it works.
