Use data to compute ΔG° at 57.0°C for the following reaction.
2ClO2−(aq) + O2(g) → 2ClO3−(aq)
ΔH°f (ClO2−(aq)) = -67 kJ mol-1
ΔH°f (ClO3−(aq)) = -104 kJ mol-1
ΔS° (ClO2−(aq)) = 101 J mol-1 K-1
ΔS° (O2(g)) = 205.152 J mol-1 K-1
ΔS° (ClO3−(aq)) = 162 J mol-1 K-1
ΔG°f (ClO2−(aq)) = 17 kJ mol-1
ΔG°f (ClO3−(aq)) = -3 kJ mol-1
ΔH°f (ClO3−(aq)) = -104 kJ mol-1
ΔS° (ClO2−(aq)) = 101 J mol-1 K-1
ΔS° (O2(g)) = 205.152 J mol-1 K-1
ΔS° (ClO3−(aq)) = 162 J mol-1 K-1
ΔG°f (ClO2−(aq)) = 17 kJ mol-1
ΔG°f (ClO3−(aq)) = -3 kJ mol-1
