Correct option is B
Sol: The correct answer is (b) 10 degrees
Key Points:
- The rate constant of a reaction doubles with a 10 degrees rise in temperature.
- This relationship is commonly observed and is supported by the Arrhenius equation, which describes how the rate constant increases with temperature.
- This is due to an increase in the number of particles that have the minimum energy required.
Arrhenius equation:
k= rate constant
A= pre-exponential factor (frequency factor)
= activation energy (the minimum energy required for a reaction to occur)
R= universal gas constant (8.314 J/mol·K)
T= absolute temperature in Kelvin
