Rate of reaction increases with increase by increasing temperature because:
Correct answer: C. Collision frequency increases
- A. The concentration of the reaction increases
- B. The activation energy of the reaction increases
- C. Collision frequency increases
- D. All of these
Explanation
The rate of a reaction increases with an increase in temperature because of the increase in kinetic energy of the reactant molecules. As the temperature increases, the kinetic energy of the reactant molecules increases, and more molecules have sufficient energy to overcome the activation energy barrier, leading to more effective collisions and a higher reaction rate.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
