Question 28

Rates of Reaction

A catalyst increases the rate of a chemical reaction by providing a path that

  1. A.raises the activation energy
  2. B.increases the temperature
  3. C.lowers the activation energy
  4. D.increases the concentration
Show the answer and explanation

Answer: C (lowers the activation energy)

Explanation

A catalyst offers an alternative route with lower activation energy, so more collisions succeed.
