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

NTA AbhyasNTA Abhyas 2020Chemical Kinetics

Solution:

Arrhenius equation $K=A.e^{- E a / R T}$

$lnK=lnA-\frac{E a}{R T}$

So, activation energy of reaction can be determined from the slope of lnK vs $\frac{1}{T}$ .

Solution

Using $y=mx+c$ we can find the value of $E_{a}$ from slope value.
