What is an adsorption isotherm?
उत्तर १
The plot between the extent of adsorption `(x/m)` against the pressure of the gas (P) at constant temperature (T) is called the adsorption isotherm.
उत्तर २
The relationship between the amount of a substance adsorbed per unit mass of adsorbent and the equilibrium pressure (in case of gas) or concentration (in case of solution) at a given constant temperature is called an adsorption isotherm.
