$100 \ mL$ of $0.6 \ M$ acetic acid is shaken with $2 \ g$ activated carbon. The final concentration of the solution after adsorption is $0.5 \ M$. The amount of acetic acid adsorbed per gram of carbon is $... \ g$.

Why is chemisorption referred to as activated adsorption?

Adsorption is accompanied by

In an adsorption experiment, a graph between $\log (x/m)$ vs $\log P$ was found to be linear with a slope of $45^{\circ}$. The intercept on the $\log (x/m)$ axis was found to be $0.3$. The amount of the gas adsorbed per gram of charcoal under a pressure of $1 \ atm$ is:

Absorption and adsorption are respectively

The validity of the Freundlich isotherm can be verified by plotting:
