1. Describe the basic assumptions of the LSW theory and discuss its results and implication.
2. Consider two separate particles with a radius of r and r2, respectively, in a liquid. Draw schematically the solute distributions in the liquid between the particles for diffusion and reaction-controlled growth, respectively. For reaction-controlled growth, are there any differences between the solute distribution in the LSW theory and those in dissolution-controlled growth and precipitation-controlled growth? Explain.
