Explanation:
Temperature Coefficient:
Temperature coefficient is the change in the rate of a chemical reaction with respect to temperature. In other words, it is the ratio of the rate constant at a given temperature to the rate constant at a temperature that is 10 degrees Celsius lower.
Range of Temperature Coefficient:
The temperature coefficient for most of the reaction lies between 2 and 3. This means that for every 10-degree Celsius increase in temperature, the rate of the reaction increases by a factor of 2 to 3.
Reasons for Temperature Coefficient:
The temperature coefficient is based on the Arrhenius equation, which states that the rate constant of a reaction is directly proportional to the temperature. This is because an increase in temperature leads to an increase in the energy of the reactant molecules, which in turn increases the frequency and energy of the collisions between the reactant molecules, leading to a higher reaction rate.
Exceptions:
There are some reactions that have a temperature coefficient outside of the range of 2 to 3. For example, some enzymatic reactions can have temperature coefficients as high as 10, while some gas-phase reactions can have temperature coefficients as low as 1. These exceptions are due to the specific nature of the reactions and the reactants involved.
Conclusion:
In conclusion, the temperature coefficient for most reactions lies between 2 and 3, indicating that the rate of the reaction increases significantly with an increase in temperature. However, there are exceptions to this rule, and the temperature coefficient can vary depending on the nature of the reaction and the reactants involved.
