The rate of a reaction becomes 4 times when temperature is raised from 293 K to 313 K. The activation energy for such reaction would be

Text Solution

Verified by Experts

`T_(1)=293 K, T_(2)=313K`
`Log""(k_(1))/(k_(2))=(E_(a))/(2.303K)((T_(2)-T_(1))/(T_(1)xxT_(2)))`
`Log 4=(E_(a))/(2.303xx8.314)xx((313-293)/(313xx293))`
`E_(a)=(0.6020xx2.303xx8.314xx313xx293)/(20)=52854.6J mol^(-1)`
`E_(a)=52.855 KJ mol^(-1)`
