Determine the reaction 2 CuO(s) ↔ 2 Cu(s) + O2(g). Data at25ºC follow. Suppose that heat capacities are independent of temperature.
ΔHºR = 314.6 kJ/mol
ΔGºR = 259.4 kJ/mol
CºP,m(CuO,s) = 42.3 J·mol-1·K-1
CºP,m(Cu ,s) = 24.4 J·mol-1·K-1
CºP,m(O2 ,g) = 29.4 J·mol-1·K-1
a. By integrating equation 6.64, dln(KP)=(ΔHR/RT^2)dT, from T0to T, show that ln[KP(T)]=ln[KP(T0)]-(ΔHR*T0/R)*(1/T-1/T0)+(T0*ΔCP/R)*(1/T-1/T0)+(ΔCP/R*ln(T/T0).
b. Determine the equilibrium pressure of oxygen over copper oxide and copper at 1350.0 K. Discuss how is this value related to KP for the reaction?
