Question

The correct option representing a Freundlich adsorption isotherm is:

विकल्प

• `x/m = kp^-1`

• `x/m = kp^0.3`

• `x/m = kp^2.5`

• `x/m = kp^-0.5`

Answer 1

`bb(x/m = kp^0.3)`

Explanation:

The Freundlich adsorption isotherm is given by the empirical equation `x/m = kp^(1//n)` where (n > 1). Here, the exponent is a positive fraction less than 1, indicating the adsorption amount increases with pressure but not linearly. Therefore, a positive fractional exponent like 0.3 fits this form, unlike negative or large exponents, which do not represent Freundlich isotherm behavior.
