For the equilibrium reaction:
2Cu(s) + SO2(g) = Cu2S(s) + O2(g),
the value of ln(PO2 / PSO2) at 973 K is: _______ (round off to 2 decimal places).
Given: ΔGo at 973 K = -100 kJ
2Cu(s) + 0.5S2(g) = Cu2S(s) ΔGo at 973 K = 292 kJ
SO2(g) = 0.5S2(g) + O2(g) R = 8.314 J mol-1K-1
Assume: Cu and Cu2S are pure solids.
2Cu(s) + SO2(g) = Cu2S(s) + O2(g),
the value of ln(PO2 / PSO2) at 973 K is: _______ (round off to 2 decimal places).
Given: ΔGo at 973 K = -100 kJ
2Cu(s) + 0.5S2(g) = Cu2S(s) ΔGo at 973 K = 292 kJ
SO2(g) = 0.5S2(g) + O2(g) R = 8.314 J mol-1K-1
Assume: Cu and Cu2S are pure solids.
Correct : -23.73
