Question
Consider a closed container with Cu(s), CuO(s), SO2(g), SO3(g), and O2(g) at 800 K. When this system reaches equilibrium, there are 3 simultaneous chemical equilibria:
(i) 2 Cu(s) + O2(g) ⇌ 2 CuO(s) Kc(i) = 1.51 × 108
(ii) CuO(s) + SO2(g) ⇌ Cu(s) + SO3(g) Kc(ii) = 6.38 × 10–6
(iii) 2 SO2(g) + O2(g) ⇌ 2 SO3(g) Kc(iii) = ?
Determine the value of the equilibrium constant Kc(iii) at 800 K.
(i) 2 Cu(s) + O2(g) ⇌ 2 CuO(s) Kc(i) = 1.51 × 108
(ii) CuO(s) + SO2(g) ⇌ Cu(s) + SO3(g) Kc(ii) = 6.38 × 10–6
(iii) 2 SO2(g) + O2(g) ⇌ 2 SO3(g) Kc(iii) = ?
Determine the value of the equilibrium constant Kc(iii) at 800 K.
