For a linear plot of log (x/m) versus log p in a Freundlich adsorption isotherm, which of the following statements is correct ? (K and n are constants)

Options

A. Both K and 1/n appears in the slope term.
B. 1/n appears as the intercept.
C. Only 1/n appears as the slope
D. log (1/n) appears as the intercept.

Answer

C

Explanation

For the Freundlich adsorption isotherm,
log (x/m) = log K + 1/n log p
On comparing with equation
Y= mx + c
slope (m) = 1/n , intercept (c ) = log K
Thus, only 1/n appears as the slope.
