According to Freundlich adsorption isotherm, the adsorption at low pressure is proporational to:

Options

A. P
B. `1//P`
C. `P^(@)`
D. `P ^(n),` (where `n =0` to 1).

Answer

A

Explanation

Frendlich adsorption isotherm is
`(x)/(m) = kP ^(1//n)`
At low pressure, the graph of `(x)/(m) vs P` is almost straight line which indicates that `x/m` is directly proportional to pressure.
`(x)/(m) prop P or (x)/(m) = kP`
