A catalyst:
Correct answer: B. Increases the rate of both forward and reverse reactions
- A. Increases the rate of the forward reaction only
- B. Increases the rate of both forward and reverse reactions
- C. Changes the equilibrium position
- D. Increases the rate of the reverse reaction only
Explanation
A catalyst increases the rate of both forward and reverse reaction, making the system reach equilibrium faster.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
