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

Options

A. `(In K)/(T)` vs. T
B. In K vs. `(1)/(T)`
C. `(T)/(In K)` vs. `(1)/(T)`
D. In K vs. T

Answer

B

Explanation

Arrhenius equation
`K=A.e^(-E_(a) // RT)implies In K=InA-(E_(a))/(RT)`
`"slope=(-E_(a))/(R)`
so, activation energy of reaction can be determined from the slope of In K vs `(1)/(T)`
