The energy of activation of a chemical reaction ?
Correct answer: B. Is the minimum energy which the molecules must have before the reaction can take place
- A. Is same as heat of reaction at constant pressure
- B. Is the minimum energy which the molecules must have before the reaction can take place
- C. Varies as fifth power of the temperature
- D. Both B. and C.
Explanation
Activation energy is the energy barrier that reacting molecules must overcome for reaction to occur. It is not the same as heat of reaction, and it does not vary as the fifth power of temperature.
