The plot of ,K Vs 1 T helps to calculate - Vidyadip

MCQ

The plot of $\log\,K$ Vs $\frac{1}{T}$ helps to calculate

A
The energy of activation
B
The rate constant of the reaction
C
The order of reaction
✓
The energy of activation as well as frequency factor

✓

Answer

Correct option: D.

The energy of activation as well as frequency factor

d
According to Arrhenius equation

$\log k=\log A-\frac{E_a}{2.303} \cdot \frac{1}{T}$

Plot of $\log k\,vs\, \frac{1}{ T }$ is a straight line.

Slope $=-\frac{ E _{ a }}{2.303 R }$

Intercept $=\log A$
