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 sides `log(x)/(m) = ((1)/(n))logp+logk`

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 logk and slope of the straight line gives the value of `(1)/(n)`
