A layer of 10 g of iodine is spread uniformly over a surface of area 10 cm? and covered in hexane to a depth of 10 cm. Diffusion coefficient of I2 in hexane is 4.05 · 10-9 m2 What will be the molar concentration of I2 at 5 cm above the original layer after: a) 10 s?; b) 24 h?; c) compare the answer in b) with the maximum concentration achieved if I2 were completely dissolved in the cubic volume 10 cm² x 5 cm and based on this comparison conclude if the diffusion will continue beyond 24 h or not
