Which among the following statements are crrect with respect to adsoption of gases or a solid? (i) The extent of adsorption is equal to kP^(n) according to Freundlich isotherm (ii) The extent of adsorption is equal to kP^(1//n) according to Freundlich isotherm (iii) The extent of adsorption is equal to (1+bP)//aP according to Langmuir adsorption isotherm (iv) The extent of adsorption is equal to ap//(1+bP) according to Langmuir isothem (v) Frecundlch adsorption isotherm fails at low pressure

Which of the following statements are correct with respect to adsorption of gases on a solid ? (i) The ectent of adsorption is equal to KP^(n) according to Freundlich isotherm. (ii) The extent of adsorption is equal to KP^(1//n) according to Frendlich isotherm. (iii) The extent of adsorption is equal to (1+bP)/aP according to Langmuir isotherm. (iv) The extent of adsorption is equal to aP/(1+bP) according to Langmuir isotherm. (v) Freundlich adsorption isotherm fails at low temperature.
