# Explain What You Understand By Temperature Coefficient

The temperature coefficient of the reaction is used to describe the effect of temperature on the rate of the reaction. The temperature coefficient of the reaction is defined as the ratio of the rate constant at two temperatures differ by 10oC, usually from 25oC to 35oC.

Temperature coefficient =

$$\begin{array}{l}\frac{Rate\ constant at (T+10)K}{Rate\ constant at\ T K}\end{array}$$

Temperature coefficient =

$$\begin{array}{l}\frac{K_{T+10}}{K_{T}}\end{array}$$

The value of the temperature coefficient for most of the reactions becomes double or triple for each 10oC rise in temperature.

When determining the temperature of the measuring object with rising or falling ambient temperature, greater attention must be given to the effects on the electronic measuring equipment. Calibrating settings at multiple different ambient temperatures should minimize the measuring error.
