Correct Answer - D
In the case of adsorption of gass on solids, the relation between `x//m` and the pressure `P` of the gas at constant temperature is given by Freundlich adsorption Isotherm:
`(x)/(m)=kP^(1//n)`
Taking logarithm on both siddes, we get
`overset("log"(x)/(m)=logK+(1)/(n)log,P)({:(darr,darr,darr,darr),(y,c,m,x):}`
Thus if we plot a graph between log `(x//m)` and log `P,a` straigh line is obtained.
The slope of the line is equal to `1//n` and the intercept on log `(x//m)` axis will correespond to log `K` .
