Which of the following statements is incorrect?
Correct answer: C. When a specific rate constant has a smaller value, then activation energy is smaller
- A. Order of reaction helps us to determine mechanism of reaction
- B. Arrhenius equation is used to determine activation energy
- C. When a specific rate constant has a smaller value, then activation energy is smaller
- D. A type of catalysis in which reactant and catalyst are in the same phase is known as homogeneous catalysis
Explanation
This statement is incorrect. Activation energy is not directly related to the specific rate constant. Activation energy is the minimum amount of energy required for a reaction to occur. It is determined by the Arrhenius equation, which relates the specific rate constant (k) to temperature and activation energy. A smaller specific rate constant does not necessarily indicate a smaller activation energy. In fact, activation energy is independent of the rate constant; it solely depends on the nature of the reaction and the transition state.
