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. Only `1//n` appears as the slope.
B. "log" (1/n) appears as the intercept.
C. Both k and 1/n appear in the slope term
D. 1/n appears as the intercept.

Answer

A

Explanation

According to Freundlich adsorption isotherm
`""log""(x)/(m)="log"K+(1)/(n)"log"P`
Thus if a graph is plotted between "log"(x/m) and "log" P, a straight line will be obtained

The slope of the line is equal to 1/n and the intercept on "log" x//m axis will correspond to "log" K
