Adsorption of CO on charcoal at 273 K follows Langmuir isotherm. A plot of $\mathrm{P}(\mathrm{kPa}) / \mathrm{V}\left(\mathrm{cm}^{3}\right)$ versus $\mathrm{P}(\mathrm{kPa})$ is linear with a slope of 0.01 y -intercept of 0.5 . The equilibrium constant, $\mathrm{K}\left(\mathrm{kPa}^{-1}\right)$, for the adsorption is ____ .
