If (x/m) is the mass of adsorbate adsorbed per unit mass of adsorbent. P is the pressure of the abdsorbate gas and a and b are constants, which of the following represents "Langmuir adsorption isotherm" ?

A

`log(x/m)=log(a/b)+1/alogp`

B

`x/m=b/a+1/(ap)`

C

`x/m=(1+bp)/(ap)`

D

`1/(x/m)=b/a+1/(ap)`

Text Solution

Verified by Experts

The correct Answer is:
D
If x/m is the mass of adsorbate per unit mass of adsorbent. P is the pressure of the adsorbate gas and a and b are constants. Then Langmuir adsorption isotherm is given as :
`" "x/m=(aP)/(1+bP)`
`or" "1/(x//m)=(1+bP)/(aP)`
`" "1/(x//m)=1/(aP)+b/a`
