The energy of activated complex is:
Correct answer: D. Higher than the energy of both the reactants and products
- A. Lower than the energy of reactants and higher than the energy of products
- B. Lower than the energy of products and higher than the energy of reactants
- C. Lower than the energy of both the reactants and products
- D. Higher than the energy of both the reactants and products
Explanation
D is correct. The energy given to initiate areaction or to form an activated complex is always higher than both reactants and products.

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.
