Question 1

Calculate the equilibrium constant for the following reaction at 525 K:

2CO(g) + O2(g) → 2CO2(g)ΔrH° = -566 kJ mol-1; ΔrS°= -173 J K-1 mol-1

◦ 7.56 × 1084
◦ 2.47 × 1014
◦ 1.90 × 1047
◦ 3.61 × 1058
◦ 8.49 × 106

Question 2

Calculate the equilibrium constant for the following reaction at 298 K:

2H2S(g) → 2H2(g) + S2(g)ΔrH° = 169.8 kJ mol-1; ΔrS°= 78.0 J K-1 mol-1

◦ 6.38 × 10-24
◦ 2.06 × 10-26
◦ 3.28 × 10-21
◦ 1.05 × 10-25
◦ 4.99 × 10-29
