Explain graphical method to determine activation energy of a reaction.

Text Solution

Verified by Experts

Arrhenius equation is In K = 1n `A - (E_(a))/(RT)`
Taking log 10, `log_(10) K = - (E_(a))/(RT) + log_(10) A`
`log_(10)` k is plotted against 1/T, the graph is straight line.
In graph slope `= A - (E_(a))/(2.303R)`
`:. E_(a) = - `slope `xx 2.303 xx R`
