The rate of reaction of a/an ______________ reaction is not affected by temperature rise ?
Correct answer: B. Photochemical
- A. Autocatalytic
- B. Photochemical
- C. Consecutive
- D. Zero order
Explanation
Photochemical reactions are initiated by absorbed light, so their rate is governed mainly by radiation intensity and quantum efficiency rather than ordinary thermal activation. Thermal, consecutive and autocatalytic reactions generally show temperature dependence.
