It is observed that for many reactions the rate constant nearly doubles for a rise in temperature of how much?
A1 degree
B5 degrees
C10 degrees
D100 degrees
Answer & Solution
Correct answer: C. 10 degrees
1. A general empirical observation in kinetics relates rate to temperature.
2. For a rise of about 10 degrees, the rate constant becomes nearly double.
3. This is explained by the larger fraction of molecules crossing $E_a$ as T rises.
