JEE Main Chemistry question
Not in JEE Main or NEET syllabus
Which among the following statements are correct with respect to the adsorption of gases on a solid?
(i) The extent of adsorption is equal to according to Freundlich isotherm. (ii) The extent of adsorption is equal to according to Freundlich isotherm. (iii) The extent of adsorption is equal to according to Langmuir isotherm. (iv) The extent of adsorption is equal to according to Langmuir isotherm. (v) Freundlich adsorption isotherm fails at low pressure, where and are constants and is pressure.
Solution
The Freundlich isotherm is , so statement (ii) is correct and (i) is not. The Langmuir isotherm is , so statement (iv) is correct while
