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 appear 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.

Explanation

According to Freundlich adsorption isotherm,
`x/m = kP^(1/n)`
`or log""(x)/m = log x + 1/n log P`
Plot of log (x/m) vs log P gives intercept = log k and slope `=1/n`, Therefore,only `1/n` appears as the slope.
