Don't copy from textbook solution.

Question 1: The rate at which solid dissolves from a flat plate of solid benzoic acid into water flowing past the solid at 300K and atmospheric pressure is found to be 1.8x10-6 kmol/m s. The solubility of benzoic acid in water is 2.95x10-2 kmol/m. The diffusivity of benzoic acid in water is 1.245x10-9 m-/s. Assuming dilute solution, calculate mass transfer coefficient K and film thickness using film theory
