Calculate the heat of crystallization, in kilojoules per mole, when 50.0 grams of sodium hydroxide (NaOH) is dissolved in 500.0 grams of water at 25⁰C and then cooled to 5⁰C, assuming that all the heat evolved during the process is transferred to the solution. The heat capacity of water is 4.18 J/gK, and the enthalpy of formation of NaOH is -425 kJ/mol.

A zinc electrode is connected to a copper electrode by a wire in a beaker that has a solution of 0.1 M CuSO4 and 0.1 M ZnSO4. The initial reduction potential of the copper electrode is +0.34 V, and the initial oxidation potential of zinc is –0.76 V. What is the potential difference between the two electrodes at 298 K, and what is the rate of the electrochemical reaction when the cell operates at a current of 2.50 A?
