As we lerant in concept

Temperature Coefficient -

In homogenous thermal reaction, the rate constant of the reaction becomes double / thrice by changing the temperature by 10^{\circ}.

- wherein

Formula:

\frac{K_{t}+10}{K_{t}}\approx2\ to\ 3

K_{t} = Rate constant of the reaction which is temperature dependent

 

 

tc^{\circ} \rightarrow \left ( t +10 \right )c^{\circ}    (2  times)

tc^{\circ} \rightarrow \left ( t +20 \right )c^{\circ}    (4   times)

tc^{\circ} \rightarrow \left ( t +30 \right )c^{\circ}     (8  times)

tc^{\circ} \rightarrow \left ( t +40\right )c^{\circ}     (16 times)

tc^{\circ} \rightarrow \left ( t +50\right )c^{\circ}      (32 times)
