Q. Freundlich equation for adsorption of gases (in amount ofX g) on a solid(in amount of m g)at constant temperature can be expressed as
A) $\log\frac{X}{m} = \log{p + \frac{1}{n}}\log k$
B) $\log\frac{X}{m} = \log{k + \frac{1}{n}}\log p$
C) $\frac{X}{m} \propto p^{n}$
D) $\frac{X}{m} = \log{p + \frac{1}{n}}\log k$
Explanation
(b)
According to Freundlich equation,
$\frac{X}{m} \propto p^{1/n}or\frac{X}{m} = kp^{1/n}$
$or\log{\frac{X}{m} = \log{kp^{1/n}}}$
or $\log\frac{X}{m} = \log{k + \frac{1}{n}}\log p$
