Which of the following statements is not correct about Freundlich ads...
Explanation:
Freundlich adsorption isotherm is an empirical equation that describes the adsorption of a solute onto a solid surface. It is given by the equation:

x/m = k p^(1/n)

where x is the amount of solute adsorbed per unit mass of adsorbent, m is the mass of adsorbent, p is the pressure of the solute in the gas phase, k and n are constants.

At low pressure, the amount of adsorbate depends linearly on pressure:
This statement is correct. At low pressure, the amount of solute adsorbed is directly proportional to the pressure of the solute in the gas phase.

At high pressure, the amount of adsorbate is independent of pressure:
This statement is incorrect. At high pressure, the amount of solute adsorbed reaches a maximum value beyond which further increase in pressure does not result in any significant increase in the amount of solute adsorbed.

The slope of log(x/m) vs. log(p) may vary from zero to one:
This statement is correct. The slope of the log(x/m) vs. log(p) curve is equal to 1/n, which can vary from zero to one depending on the nature of the adsorbate-adsorbent interaction.

The most probable value of (1/n) is around one:
This statement is incorrect. The value of 1/n can vary widely depending on the nature of the adsorbate-adsorbent interaction. In general, values of 1/n between 0.1 and 1 are observed.

Therefore, the correct answer is option 'D'.

Which of the following statements is not correct about Freundlich ads...
According to Freundlich isotherm, (x/m) = kp1/n; where n > 1.
At low pressure, the isotherm is approximately linear, so (x/m) depends linearly on pressure and at high pressure (x/m) becomes constant.
So, (x/m) is almost independent of pressure.
The slope of log (x/m) vs. log(p) curve is 1/n. Since the value of 1/n varies from 0 to 2, the slope may vary from 0 to 1.
But in most cases the value of 1/n lies between 0.1 and 0.5.

Read the passage given below and answer the following questions:Adsorption depends on the nature of the adsorbent. The rough solid surface has more number of pores and adsorb more number of gases than the smooth surface. Most common adsorbents are silica gel, activated charcoal. The extent of adsorption also depends on the surface area of solid. Specific surface area of an adsorbent is the surface area available for adsorption per gram of the adsorbent. The greater the surface area of the solid, the greater would be the adsoprtion. Charcoal is a more effective adsorbent than solid wood. Desorption is a process of removing an adsorbed substance from a surface on which it is absorbed.Physisorption is non-specific and any gas can be adsorbed. But the gases which are easily liquefiable (e.g., NH3, HCl, CO2) are adsorbed at a faster rate and to a large extent than the gases which are difficult to liquefy (e.g., H2, O2, N2). It depends on the critical temperature. Higher the critical temperature of a gas, more easily liquefiable it is and more is the rate of adsorption. Chemisorption is specific in nature. Therefore, only those gases can be adsorbed which are capable of forming chemical bonds with the adsorbent.The following questions are multiple choice questions. Choose the most appropriate answer:Q. Select the correct statement regarding desoprtion.
