At high pressure ,Langmuir adsorption isotherm takes the form :

Options

A. `(x)/(m) = (ap)/(1+bp)`
B. `(x)/(m) = (a)/(b)`
C. `(x)/(m) =ap`
D. `(m)/(x) = (b)/(a) +(1)/(ap)`

Answer

B

Explanation

Langmuir adsorption isotherm, is
`(x)/(m) = (ap)/(1+bp)`
At high pressure, 1+bp = bp
or `(x)/(m) = (ap)/(bp) = (a)/(b)`
