Which one of the following does NOT influence rate of reaction?
Correct answer: D. Activation energy
- A. Concentration
- B. Temperature
- C. Catalyst
- D. Activation energy
Explanation
Option d is correct because activation energy does not directly influence the rate of reaction. Instead, it is a property specific to a particular reaction pathway.

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.
