What is the energy of activation of a reaction is its rate doubles when the temperature is raised from 290 K to 300 K ?

A

12 kcal

B

15 kcal

C

10 kcal

D

20 kcal

Text Solution

Verified by Experts

The correct Answer is:
A
` log.(k_(2))/(k_(1))=(E_(a))/(2.303R)[(T_(2)-T_(1))/(T_(1)T_(2))]`
`log2=(E_(a))/(2.303xx2)[(300-290)/(290xx300)]`
`E_(a)`=12062 cal
=12.0 cal
