Role of a catalyst in a chemical reaction is to:
Correct answer: A. Increase rate of a reaction
- A. Increase rate of a reaction
- B. Decrease rate of reaction
- C. Decrease yield of a reactant
- D. Increase yield of product
Explanation
A positive catalyst increase rate of reaction, decreases activation energy, decrease equilibrium time and changes mechanism of reaction.

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.
