A crystal of copper sulphate CuSO4 5H2O falls through a large tank of pure water at 200C. Estimate the rate at which the crystal dissolves calculating the flux of CuSO4 from crystal surface to the bulk solution. Repeat by calculating the flux of water.
Data and Assumptions: Molecular diffusion occurs through a film of water 0.0305 mm thick, surrounding the crystal. At the inner side of the film adjacent to the crystal surface the concentration of copper sulphate is its solubility value, 0.0229 mole fraction of CuSO4 (Solution density 1193 kg/m3 ). The outer surface of the film is pure water. The diffusivity of CuSO4 is 7.29 × 10-10 m2 /s.

Explanation:
photosynthesis is the process in which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. photosynthesis in plants generally involve the green pigment chlorophyll and generates oxygen as by-product.
