The correct option representing a Freundlich adsorption isotherm is
Options
- Ax m =k p^ 0.3
- Bx m =k p^ 2.5
- Cx m =k p^ -0.5
- Dx m =k p⁻¹
Correct answer
A. x m =k p^ 0.3
Step-by-step solution
According to Freundlich adsorption isotherm, x m = kp ^ 1 / n where, x m = amount of the gas adsorbed per unit mass of adsorbent p = pressure k and n = constants. The value of n lies in between 0 to 1 . Thus, x m = kp ^ 0.3 and option (1) is correct.
