NEET levelSingle correct optionDifficulty 1 of 3sc011

For the Freundlich isotherm, a plot of $lo g (x / m)$ against $lo g p$ is a straight line whose slope is:

A $1/ n$
B $n$
C $k$
D $lo g k$

Answer: A

Taking logs of

x / m = k p^{1/ n}

gives

lo g (x / m) = lo g k + (1/ n) lo g p

. The slope is

1/ n

and the intercept on the

lo g (x / m)

axis is

lo g k

.
