The temperature coefficient of most of the reactions lies between:

The temperature coefficient is the ratio of the rate constant of a reaction at a temperature and the rate constant of the reaction when the temperature increases by \(10^0\) C.

Let’s suppose a reaction:

\(A  +  B ------→ C\)

Let K be the rate constant of the above reaction at temperature \(T\)

On increasing the temperature by \(10^0\)C,

The new temperature will be \(T + 10^0\)

Let the rate constant at a new temperature of the above reaction be \(K_{(T+10^0)}\)

So, the temperature coefficient of the reaction will be:

Temperature coefficient: \(\frac{K}{K_{(T+10^0)}}\)

The temperature coefficient of most of the reactions lies between 2 and 3 more precisely.
