In summary, an adsorption isotherm is a graph that shows the relationship between the amount of gas or solute adsorbed onto a solid surface and the pressure or concentration of the gas or solute at a constant temperature. The y-axis of an adsorption isotherm is represented by n/w, which indicates the amount of adsorbate per unit mass of the adsorbent. This is used to account for the amount of adsorbent used in the experiment for a more accurate comparison of data. The slope of an adsorption isotherm indicates the strength of the adsorption, with a steeper slope indicating a higher affinity. The maximum point on the isotherm can be used to determine the adsorption capacity of

No idea about the definition of 'n' and 'w' but the meaning of the y-axis is 'coverage'.
edit: it could be that 'n' means moles of absorbing species and 'w' means weight of adsorbent.

The n/w on the y-axis in an adsorption isotherm refers to the amount of adsorbate (such as gas or liquid) adsorbed per unit weight of the adsorbent material. In other words, it represents the amount of adsorbate molecules that are bound to the surface of the adsorbent material, relative to the weight of the adsorbent. This parameter is important in determining the efficiency and capacity of the adsorbent material for a particular adsorbate.
Related to Adsorption Isotherm: What Does n/w Mean on Y-Axis?
1. What is an adsorption isotherm?
An adsorption isotherm is a graph that shows the relationship between the amount of gas or solute adsorbed onto a solid surface and the pressure or concentration of the gas or solute at a constant temperature.
2. What does n/w mean on the y-axis of an adsorption isotherm?
n/w on the y-axis represents the amount of gas or solute adsorbed per unit mass of the adsorbent (usually in units of moles per gram).
3. Why is n/w used instead of just n on the y-axis?
n/w is used to account for the amount of adsorbent used in the experiment. Since different amounts of adsorbent can be used in different experiments, using n/w allows for a more accurate comparison of data.
4. What does the slope of an adsorption isotherm signify?
The slope of an adsorption isotherm represents the affinity or strength of the adsorption between the adsorbent and the adsorbate. A steeper slope indicates a higher adsorption affinity.
5. How is the adsorption capacity of an adsorbent determined from an adsorption isotherm?
The adsorption capacity of an adsorbent can be determined by finding the maximum point on the isotherm, which represents the maximum amount of adsorbate that can be adsorbed onto the adsorbent at the given conditions.
