Slope of the straight line obtained by p...

Slope of the straight line obtained by plotting `log_(10)` k against 1/T represents what term ?

A

`-E_a`

B

`-2.303 E_(a)//R`

C

`-E_(a)//2.303 R`

D

`E_a //R`

Text Solution

Verified by Experts

The correct Answer is:
C
In K = In `A-(E_a)/("RT")`
`"log"_(10)k =log_(10)A - E_(a)/("3.303 RT")`
`"log"_(10)k = (-E_a)/("2.303 RT") xx 1/T + log_(10)A`
`C = log_(10) A`
`m = slope =(-E_a)/(" 2.303 R")`
