For a second order reaction, $2 A \to$ Products, a plot of log $t_{1 / 2}$ vs log a (where, 'a' is initial concentration) will give an intercept equal to which one of the following?

Options:

Answer:

Solution:

Kinetic equation for second order reaction is
$k = \frac{1}{t} [\frac{1}{(a - x)} - \frac{1}{a}]$
when $x = \frac{a}{2}$
$t = t_{1 / 2}$

So $t_{1 / 2} = \frac{1}{k} \times \frac{1}{a}$
$\log t_{1 / 2} = - \log k - \log a$
Here intercept = log k
