1.

Which among the following statement are correct with respect to adsorption of gases on a solid ? (1) The extent of adsorption is equal to kp^(n) according to Freundlich isotherm (2) The extent of adsorption is equal to kp^(1//n) according to Freundlich isotherm (3) The extent of adsorption is equal ((a+bp))/(ap) according to Langmuir isotherm The extent of adsorption is equal (ap)/((1+bp)) according to Langmuir isotherm (5) Freundlich adsorption fails at a low pressure

Answer»

1 and 3
1 and 4
2 and 3
2 and 4

Solution :According to FREUNDLICH ISOTHERM,
`(x)/(m)=kp^(1//n)`
According to Langmuir isotherm,
`(x)/(m)=(ap)((1+bp))`
