The activation energy for a hypothetical...

The activation energy for a hypothetical reaction `A rarr X` is `12.49 kcal mol^(-1)`. If temperature is raised to `305` form `295 K`, the reaction rate increased by `0.002 kcal L^(-1) mol^(-1)` is almost equal to

A

`60%`

B

`50%`

C

`100 %`

D

Unpredictable

Text Solution

Verified by Experts

The correct Answer is:
C

The rate of reaction becomes doubled for `10^(@)C` rise in temperature. Hence, `100%` increase in reaction rate.
