How long will it take to produce 78.0 g of Al metal by the reduction of Al3+ ions in an electrolytic cell with a current of 2.00 amperes? (Al: 26.98 g/mol)

Using the standard entropy values: SO2(g), S° = +248.0 J mol−1 K−1 SO3(g), S° = +256.0 J mol−1 K−1 NO(g), S° = +210.6 J mol−1 K−1 NO2(g), S° = +240.5 J mol−1 K−1Calculate the standard entropy change, ΔS°, for the reaction: NO2(g) + SO2(g) → NO(g) + SO3(g)
