Catalytic action in a catalytic chemical reaction follows from the ability of catalyst to change the ___________________?
Correct answer: A. Activation energy
- A. Activation energy
- B. Equilibrium constant
- C. Heat of reaction
- D. None of these
Explanation
A catalyst provides an alternative reaction pathway with a lower activation energy, increasing the forward and reverse rates. It does not change the equilibrium constant or the heat of reaction.
