Using the following data determine the temperature (in K) at which the reaction H2O(g)+ C(s,graphite) ↔ H2(g) + CO(g) this becomes spontaneous.
ΔfH° (H2O(g)) = -251.2 kJ mol-1
ΔfH° (C(s,graphite)) = 0.0 kJ mol-1
ΔfH° (H2(g)) = 0.0 kJ mol-1
ΔfH° (CO(g)) = -110.1 kJ mol-1
S° (H2O(g)) = 192.6 J K-1 mol-1
S° (C(s,graphite)) = 6.4 J K-1 mol-1
S° (H2(g)) = 136.9 J K-1 mol-1
S° (CO(g)) = 192.4 J K-1 mol-1
