Which of the following curves is in according with Freundlich adsorption isotherm?

Options

A.
B.
C.
D.

Answer

C

Explanation

According to the Freundlich adsorption isotherm
`(x)/(m)=kp^((1)/(n))`
Taking log on both side `{:("log"(x)/(m),=,((1)/(n)),logp,+,logk),(uarr,,uarr,uarr, ,uarr),(Y,=,m,x,+,C):}`

On comparing it with equation of straight line and drawing the graph `"log"(x)/(m)` versus `"log"p`, we get a straight line with intercept log k and slope of the straight line gives the value of ` (1)/(n)`.
