Question

According to the Arrhenius equation, a straight line is to be obtained by plotting the logarithm of the rate constant of a chemical reaction $\left(\log k\right)$ against:

• A. $T$
• B. $\log T$
• C. $\frac{1}{T}$
• D. $\log \frac{1}{T}$

Answer 1

The correct option is C $\frac{1}{T}$

According to the Arrhenius equation, a straight line is to be obtained by plotting the logarithm of the rate constant of a chemical reaction $\left(\log k\right)$ against $\frac{1}{T}$.
Arrhenius equation is $logk=logA-\frac{E_a}{2.303RT}$
Slope $=-\frac{E_a}{2.303R}$
$Y$ intercept $=logA$
