A maximum of 1.89 mg of AgCl will dissolve in 1.00 L of solution at 25.0 C. A maximum of 5.26 mg of AgCl will dissolve in 1.00 L of solution at 50.0 C. Use this information to calculate standard enthalpy changeandstandard free energy changefor the following reaction.AgCl(s)-> Ag^+(aq) + Cl-(aq)Assume that the enthalpy and free energy changes are independent of temperature
