# 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) Option 1) Both k and 1/n appear in the slope term.   Option 2) 1/n appears as the intercept.   Option 3) Only 1/n appears as the slope.   Option 4)  log (1/n) appears as the intercept.

As we learnt in

Logarithmic graph of Freundlich isotherm -

$log\frac{x}{m}= log K+\frac{1}{n}log p$

- wherein

The slope of the straight line gives the value of 1/n. The intercept on y-axis gives the value of log K.

If a graph is plotted between log $\frac{x}{m}$ and logP a staright line will be obtained.

Option 1)

Both k and 1/n appear in the slope term.

This option is incorrect.

Option 2)

1/n appears as the intercept.

This option is incorrect.

Option 3)

Only 1/n appears as the slope.

This option is correct.

Option 4)

log (1/n) appears as the intercept.

This option is incorrect.
