Mg(s) + Fe?+ (aq) --Mg(aq) +- Fe(s) + Express your answer to three significant figures and include the appropriate units. ► View Available Hint(s) Free-energy change AG is related to coll potential, E by the equation AG-FE whoron is the number of moles of electrons transferred and F-96,500 C/(mole ) is the Faraday constant. When Els measured in volts, AG must be in joules since 1 J 10 V AGE -3.71x10 J mol Previous Answers ✓ Correct Sinon Eis positive and AG is negative, this reaction is spontaneous under standard condition Part B Calculate the standard coll potential at 25°C for the reaction *(s) + 2Y"(aq) --X(aq) + 2Y() where AH-787 kJ and AS - 261J/K Express your answer to three significant figures and include the appropriate units. ► View Available i NA Value Onits Submit

The equilibrium constant, K for a redox reaction is related to the standard potential, E, by the equation K = 268x10 In K = nFE Previous Answers RT where n is the number of moles of electrons transferred F (the Faraday constant) is equal to 96,500 C/(mole).R (the gas constant) is equal to 8.314 J/(mol K) and Tis the Kolvin temperature ✓ Correct When Eº > 0 and K > 1 the reaction favors the products, Part B Calculate the standard cell potential (E") for the reaction X(s) +Y+ (aq)+X+ (aq) +Y() # K = 1.13x10-> Express your answer to threo significant figures and include the appropriate units.
