Assertion : Temperature coefficient of a reaction℃

A → B is given as $\frac{k _{35℃}}{k _{25℃}} = 2$ for a higher temperature range, $\frac{k _{95℃}}{k _{85℃}} < 2$ .

Reason: The effect of temperature on $k$ is given by the Arrhenius equation $k = A e^{- E_{a} / RT}$ .

Answer:

Solution:

The rate increase is more at lower range of temperature as compared to a higher range of temperature.
