Solution
Correct Answer:
2
The Temperature Coefficient of a reaction is defined as the ratio of rate constants at two temperatures differing by 10∘C. Temperature Coefficient=kTkT+10
- Given that the rate doubles for every 10∘C rise in temperature.
- Since Rate ∝k, then RateTRateT+10=kTkT+10=2.
- Most chemical reactions have a temperature coefficient between 2 and 3.
This easy difficulty chemistry question is from the chapter chemical kinetics, covering the topic of temperature effect. It appeared in the 2025 exam.
