Question 1

Determine the equilibrium constant for the following reaction at 498 K:

2 Hg(g) + O2(g) → 2HgO(s)ΔrH° = -304.2 kJ mol-1; ΔrS° = -414.2 J K-1 mol-1

◦ 5.34 × 10-11
◦ 2.31 × 10-22
◦ 1.87 × 1010
◦ 8.10 × 1031
◦ 4.33 × 1021

Question 2

Determine the equilibrium constant for the following reaction at 655 K:

HCN(g) + 2H2(g) → CH3NH2(g)ΔrH° = -158 kJ mol-1; ΔrS°= -219.9 J K-1 mol-1

◦ 2.51 × 10-13
◦ 13.0
◦ 3.07 × 1011
◦ 3.26 × 10-12
◦ 3.99 × 1012
