With the increase in temperature the rate of reaction increases due to
Correct answer: D. More number of molecules attain activation energy
- A. Decrease in collisions
- B. Decrease in activation energy
- C. Increase in kinetic energy of the molecules
- D. More number of molecules attain activation energy
Explanation
As the temperature rises, a larger proportion of the molecules have energy equal to or greater than the activation energy, allowing them to participate in the 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.
