(i)
Write the expression for adsorption of gases on solids in the form of an equation.
(ii)
What is the slope of the graph ?
(iii)
What does the intercept of the line represent?
Marking-scheme solution
(i) \(\displaystyle \log \frac{x}{m}=\log K+\frac{1}{n} \log P\)
(ii) Slope \(\displaystyle =\frac{1}{n} \quad\) or \(\displaystyle \mathrm{b} / \mathrm{a}\)
(iii)
Intercept = log K
