Question

Data for the adsorption of ethylene on activated charcoal at 298 K can be shown to fit the Langmuir equation. In a series of experiments, data were fitted to the linear form of the Langmuir equation, and the slope was found to have the value 132.3 mol–1 with an intercept of 131.0 mol–1 (for one gram of charcoal). One molecule can be assumed to occupy 0.21 nm2 of surface. a. Calculate the surface area of one gram of charcoal in units of m2
