The activation energy of a reaction can be determined from the slope of which of the following graphs

Options

(a) lnK/T vs.T
(b) ln K vs.1/T
(c) T/ln K vs.1/T
(d) ln K vs .T

Correct Answer:

ln K vs.1/T

Explanation:

Arrhenius equation
K=A.e(-Eₐ/RT⇒In K =In A -Eₐ/RT
slop = -Eₐ/R
so,activation energy of reaction can be determined from the slop of In K vs 1/T.
