(a) Dispersed phase = liquid ;
Dispersion medium $=$ liquid
(b) Because adsorption leads to a decrease in the residual forces on the surface of the adsorbent. This causes a decrease in the surface energy of the adsorbent. Therefore, adsorption is always exothermic.
(c) $\log \frac{\mathrm{x}}{\mathrm{m}}=\log \mathrm{k}+\frac{1}{\mathrm{n}}\log \mathrm{p}$
At high pressure $\frac{\mathit{x}}{\mathit{m}}\mathrm{\alpha }{\mathrm{p}}^{\circ }$
