Ea appears as a potential energy hill between _ for carrying out the reaction
Correct answer: B. Reactants and the products
- A. Reactants and activated complex
- B. Reactants and the products
- C. Products and the activated complex
- D. Reactants
Explanation
The activation energy is the minimum energy required to initiate a chemical reaction, appearing as a potential energy hill between the reactants and the products. It represents the energy needed to reach the activated complex, which is the highest energy state in the transition from reactants to products. Other options are incorrect because they misrepresent the energy transition or fail to capture the complete process from reactants to 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.
