If energy of the activated complex is close to energy of reactants, it means that the reaction is:
Correct answer: A. Fast
- A. Fast
- B. Moderate
- C. Slow
- D. Very slow
Explanation
Activated complex is formed once the activation energy is reached by the reactants. If there is a small difference in energy of the activated complex and that of reactants, the reaction will proceed fast because little additional energy will be required by the reactants to overcome the activation energy barrier and subsequently complete the reaction in a short duration. Therefore, option A is the correct answer.

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.
