Question 1

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

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

◦ 3.84 × 10-11
◦ 1.51 × 10-13
◦ 6.18 × 10-15
◦ 4.08 × 10-17
◦ 7.52 × 10-19

Question 2

Determine the equilibrium constant for the following reaction at 549 K:

CH2O(g) + 2H2(g) → CH4(g) + H2O(g) ΔrH° = -94.9 kJ mol-1; ΔrS°= -224.2 J K-1 mol-1

◦ 9.35 × 10-10
◦ 1.94 × 10-12
◦ 481
◦ 2.08 × 10-3
◦ 1.07 × 109
