The minimum amount of energy required for an effective collision is called activation energy. Which one of the following statements is incorrect about activation energy?Ea =Activation energy K = Specific rate constant
Correct answer: C. Ea is directly proportional to k
- A. Ea of exothermic reaction in the forward reaction is less than that of backward reaction
- B. Ea of endothermic reaction in the forward direction is greater than that of reverse reaction
- C. Ea is directly proportional to k
- D. Ea is independent of temperature
Explanation
The activation energy and the rate constant have an inverse relation. So, the C option is our correct answer since the relation written is incorrect.

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.
