Effect of catalystEasyQuestion 600405

Question

Adding a catalyst to an equilibrium reaction:
  1. A
    Increases Kc
  2. B
    Decreases Kc
  3. C
    Speeds up both forward and reverse reactions equally
    Correct
  4. D
    Changes the position of equilibrium

Correct answer

Speeds up both forward and reverse reactions equally

Explanation

A catalyst lowers activation energy for both forward and reverse reactions equally, reaching equilibrium faster but NOT changing K or equilibrium position.
