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

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

Correct answer: Only 1/n appears as the slope

Solution

In the Freundlich adsorption isotherm, the relationship between log(x/m) and log(p) is linear, where the slope is determined solely by the constant 1/n, indicating the degree of adsorption. The constant k influences the intercept but does not contribute to the slope.
