Solution

Q.
The activation energy of a reaction can be determined from the slope of which of the following graphs [2015]

1 $\ln k$ $vs$ $\frac{1}{T}$

2 $\frac{T}{\ln k}$ $vs$ $\frac{1}{T}$

3 $\ln k$ $vs$ $T$

4 $\frac{\ln k}{T}$ $vs$ $T$

Ans.
(1)

According to Arrhenius equation,

$k = A e^{- E_{a} / R T}$

$\ln k = \ln A - \frac{E_{a}}{R T}$

Hence, if ln $k$ is plotted against 1/T, slope of the line will be $- \frac{E_{a}}{R} .$
