उत्तर
Explanation:
To arrhenius equation `k = A e^((-Ea)/(RT)`
Taking log on both sides in `k` = In `A.e^(-(E_a)/(RT))`
In `k` = In `A - (E_a)/(RT)`
In `k = - (-E_a)/R xx 1/T` + In A
y = mx + c
This equation can be related to equation of straight line.
From the graph, it is very clear that slope of the plot = `(-E_a)/R` and intercept = In A.
