If a reation follows the Arrhensis equation the plot lnk vs`1/(RT)` gives straight line with a gradient (-y) unti .The energy required to active the reactant is :

A

`-y` unit

B

yR unit

C

y unit

D

y/R unit

Text Solution

Verified by Experts

The correct Answer is:
C
`k=Ae^(-Ea//RT)`
In k = In `A-E_(a)//RT`
Slope `=-E_(a)`
`-E_(a) =-y" "therefore E_(a)` =y unit
