Activation energy of a reaction:
Correct answer: D. Required for effective collisions
- A. Includes the average kinetic energy of the reaction
- B. Is in addition to the average K.E. of the reactants
- C. Is in addition to the average K.E. of the products
- D. Required for effective collisions
Explanation
The minimum amount of energy required by the colliding molecules for effective collision is called activation energy.

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.
