langmuir isotherm merits and demerits

Langmuir adsorption isotherm is based on the following assumptions. i) Adsorption does not proceed beyond monolayer coverage. ii) All the sites available on the adsorbent surface are equivalent and the surface is perfectly uniform, that is fla..

Langmuir adsorption isotherm is based on the following assumptions. i) Adsorption does not proceed beyond monolayer coverage. ii) All the sites available on the adsorbent surface are equivalent and the surface is perfectly uniform, that is flat. iii) The ability of a gas molecul..

Merits: s is based on every item of the data. s takes care of both positive and negative deviation. Demerits: s is some what not easy to understand. The extreme values unduly affect s..

Merits: - Mean deviation is easy to calculate. This measure is simple to understand. This can be calculated from any average. Its value is based upon all the (observations) items of the data. It is less affected by extreme observations. It gives us an idea about how the items are situated..

The five-kingdom classification has certain merits and demerits. However, it is largely the most accepted system of modern classification mainly because of the phylogenetic placing of different groups of living organisms. This system of classification looks more scientific and n..

Introduction - Today graphics, tables, reasoning, estimation and prediction are playing a very important role in stating the facts in terms of figures. Statistics deals mainly in communicating facts and figures in terms of a method called statistical method. Collection, classification, tabulation, ..

The natural system of classification has been subjected to periodic reviewing as a result of the continuous input of information and new scientific tools being available on various aspects of living organisms. Various schemes of classification are now available, each having certain merits..

) Specific area of the adsorbent. Specific area of an adsorbent is the surface area available for adsorption per gram of the adsorbent. As discussed before, specific area of the adsorbent increases tremendously when finely divided forms of the solid adsorbent are used. Porous solids are very good a..
