Which plot of $\ln k$ vs $\frac{1}{\mathrm{~T}}$ is consistent with Arrhenius equation?
Which plot of $\ln k$ vs $\frac{1}{\mathrm{~T}}$ is consistent with Arrhenius equation?
Solution
The Arrhenius equation is given as
$\begin{aligned}
& k=A e^{-\frac{E_a}{R T}} \\
& \therefore \quad \ln k=\ln A-\frac{E_a}{R T}
\end{aligned}$
In $\mathrm{k} v / \mathrm{s} \frac{1}{\mathrm{~T}}$ gives a straight line graph with slope $=-\frac{E_{\mathrm{a}}}{R}$ and intercept $=\ln \mathrm{A}$
