A plot of `(1)/(T)` Vsk for a reaction gives the slope `- 1 xx 10^(4)K`. The energy of activation for the reaction is
(Given `R = 8.314 JK^(-1) " mol"^(-1)`)

A

8314 J `mol^(-1)`

B

`1.202 kJ mol^(-1)`

C

`12.02 J mol^(-1)`

D

`83.14 kJ mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
(A) The slope of In`(1)/(T)` vs k graph `= (-Ea)/( R)= -1xx10^(4)`
or ` E_(a)= Rxx10^(4) `
`= 8.314xx10^(4)JK^(-1) mol^(-1)`
`=8.314 J K^(-1) mol^(-1)`
