The rate of formation of nuclei and the rate of crystallization is affected by the nature of the crystallizing substance, the concentration, the temperature, agitation, and the impurities present in the solution. Explain how the nature of the crystallizing substance and temperature will influence the crystallization process. (6 marks)
