(C) The Freundlich adsorption isotherm is given by the equation: $\frac{x}{m} = k 	imes p^{\frac{1}{n}}$.Taking the logarithm on both sides,we get: $\log(\frac{x}{m}) = \log(k) + \frac{1}{n} \log(p)$.This equation represents a straight line of the form $y = mx + c$,where the slope is $\frac{1}{n}$.If the slope is zero,then $\frac{1}{n} = 0$.Substituting this into the original equation: $\frac{x}{m} = k 	imes p^0 = k$.Since $\frac{x}{m}$ is constant and does not depend on $p$,the extent of adsorption is independent of the pressure of the gas.

In the adsorption of a gas on a solid,the Freundlich isotherm is obeyed. If the slope of the plot of $\log(\frac{x}{m})$ versus $\log(p)$ is zero,then the extent of adsorption is:
