MCQ
Which plot of $\ln \mathrm{k}$ vs $\frac{1}{\mathrm{~T}}$ is consistent with Arrhenius equation?
- A
- B
- ✓
- D
✓
Answer
Correct option: C.
c
The Arrhenius equation is given as
The Arrhenius equation is given as
$ k=A e^{-\frac{E_a}{R T}} $
$ \therefore \quad \ln k=\ln A-\frac{E_a}{R T}$
In $\mathrm{kv} / \mathrm{s} \frac{1}{\mathrm{~T}}$ gives a straight line graph with slope $=-\frac{E_a}{R}$ and intercept $=\ln \mathrm{A}$
