Which of the following graphs represents freundlich adsorption isotherm?

Options

A.
B.
C.
D.

Answer

A

Explanation

According to Freundlich adsorption isotherm, `x//m= k_(p^((1)/(n)))`
Where, x= mass of gas adsorbed on mass .m. of the absorbent at pressure p. k and n= constants
Taking logarithm on both sides, we get `log x//m= log k+ (1)/(n) log p`
This is equation of a straight line with slope of `(1)/(n)` and intercept of log k.
