What is the cell potential for the reaction Mg(s) + Fe2+(aq) rightarrow Mg2+(aq)

Question

What is the cell potential for the reaction Mg(s) + Fe2+(aq) rightarrow Mg2+(aq) + Fe(s) at 85 degree C when [Fe2+] = 3.80M and [Mg2+] = 0.310M . Express the potential numerically in volts. Try Again; 4 attempts remaining 2Ca (s) + O2 (g) rightarrow 2CaO(s) Delta H degree rxn = -1269.8 kJ; Delta S degree rxn = -364.6 J/K Calculate the free energy change for the reaction at 26 degree C. Express your answer using four significant figures. Try Again; 5 attempts remaining Is the reaction spontaneous? spontaneous nonspontaneous
