The Arrhenius equation is,

k = A \cdot e^{- E_{a} / RT}

where,

k =

rate constant,

A =

Arrhenius constant,

E_{a} =

activation energy, and

T =

temperature in

K

From the equation, it is clear that

k

decreases exponentially with

E_{a}

. So, the plot-I is correct. In the plot-II,

k

is plotted with temperature (in

^{\circ} C

but not in

K)

. So, at

0^{\circ} C, k \neq = 0

and

k

will increase exponentially with temperature upto

30 0^{\circ} C

. Therefore, the plot-ll is also correct.
