Question

The temperature dependence of rate constant (k) of a chemical reaction is written in terms of Arrhenius equation $k = A e^{- E / R T}$ . Activation energy $(E_{a})$ of the reaction can be calculated by plotting:

Solution

The correct option is B log k vs $∙$ $\frac{1}{T}$
$k = A e^{-^{E a / R T}}$
$l o g k = l o g A \frac{- E a}{R T} \times l o g e$
by plotting
$l o g k v s \frac{1}{T}$
its slope will give $\frac{E a}{R}$
by that we can calculate Ea
