Problem 2: The following data refer to the adsorption of the red-mauve dye from beetroot juice on porcelain at 25C. 2.1 Show that the data obey the Langmuir adsorption isotherm. 2.2 Demonstrate that 1.2108mol of dye adsorb to form a monolayer. 2.3 Estimate the area of a single dye molecule if the radius of a plate was 17.8 cm (we assume the formation of a complete monolayer)
