Increasing the temperature increases the rate of reaction by:
Correct answer: D. Increasing the frequency or effective collision between reactive molecules
- A. Lowering the activation energy
- B. Increasing the activation energy
- C. Lowering the frequency or effective collisions between reactive molecules
- D. Increasing the frequency or effective collision between reactive molecules
Explanation
This option is correct. Increasing the temperature provides more kinetic energy to the molecules, leading to higher collision frequency and more effective collisions. As a result, the rate of reaction increases.

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.
