Adsorption of a gas on solids follows Freundlich adsorption isotherm. The graph drawn between $\log \frac{x}{m}$ (on $y$-axis) and $\log p$ (on $x$-axis) is a straight line with slope equal to 3 and intercept equal to 0.30 . What is the value of $\frac{x}{m}$ at a pressure of 2 atm ?

(Given: $\log 2=0.3$ )

In a colloidal solution, both the dispersed phase and dispersion medium are in liquid phase. What is the type of colloid?

The equation which represents Freundlich adsorption isotherm is ( $x=$ amount of gas, $m=$ mass of solid)
