What effect does a change in the concentration of ligands have on the formation of a complex ion in a solution of FeCl3? How does this affect the equilibrium constant of the reaction and what is the relationship between the concentration of the ligands and the stability constant of the complex ion? Calculate the equilibrium concentrations of the species involved and determine their values at different stages of the reaction. Use the given data and appropriate equations to solve the problem.

A chemistry student needs to determine the conditions at which a pure substance will change from solid to liquid phase. The substance in question has a melting point of 120 °C and a heat of fusion of 35 kJ/mol. How much heat is required to melt 100 grams of the substance at its melting point? And, what is the temperature at which the substance will start to solidify if the ambient pressure is 1 atm and the substance has cooled from its liquid phase at 150 °C to its solid phase?
