Vedclass · Answer

(B) The Langmuir adsorption isotherm is given by the equation: $\frac{x}{m} = \frac{ap}{1 + bp}$.Rearranging this equation,we get: $\frac{1}{x/m} = \frac{1 + bp}{ap} = \frac{1}{ap} + \frac{b}{a}$.Alternatively,multiplying by $p$,we get: $\frac{p}{x/m} = \frac{1 + bp}{a} = \frac{1}{a} + \frac{b}{a}p$.Comparing this with the equation of a straight line $y = mx + c$,where $y = \frac{p}{x/m}$ and $x = p$,we see that the plot of $\frac{p}{x/m}$ versus $p$ is a straight line with slope $\frac{b}{a}$ and intercept $\frac{1}{a}$.

According to the Langmuir adsorption isotherm,which of the following plots is a straight line?
