The energy of activation of exothermic reaction is_________________?
Correct answer: B. Not possible to predict
- A. Zero
- B. Not possible to predict
- C. Very large compared to that for endothermic reaction
- D. Negative
Explanation
The sign or magnitude of activation energy cannot be determined merely from whether a reaction is exothermic or endothermic; it depends on the reaction pathway and energy barrier. Therefore, it is not possible to predict it from the information given.
