Freundlich adsorption isotherm is given by the expression

\frac{x}{m} = KP{\,^{1/n}}

, which of the following conclusions can be drawn from this expression.
a) When,

\frac{1}{n} = 0

, the adsorption is independent of pressure
b) When,

\frac{1}{n} = 0

, the adsorption is directly proportional to pressure
c) When,

n = 0,{\mkern 1mu} \frac{x}{m}\,\,VS

P graph is a line parallel to x-axis
d) When, n = 0, plot of

\frac{x}{m}VS\,\,\,P

is a curve

View answer and explanation

Correct option: B

a,c

Option B (a,c) is correct because when 1/n = 0, adsorption is independent of pressure, and when n = 0, the x/m vs P graph is a line parallel to the x-axis.
