Question 1

Use Hess's law to calculate ΔrG° using the following information:

ClO(g) + O3(g) → Cl(g) + 2O2(g)ΔrG° = ?
2O3(g)→ 3O2(g)ΔrG° = +489.6 kJ mol-1
Cl(g) + O3(g) → ClO(g) + O2(g)ΔrG° = -34.5 kJ mol-1

◦ -210.3 kJ mol-1
◦ +262.1 kJ mol-1
◦ +524.1 kJ mol-1
◦ -472.4 kJ mol-1
◦ +455.1 kJ mol-1

Question 2

Calculate ΔrG° at 298 K using the following information:

2HNO3(aq) + NO(g) → 3NO2(g) + H2O(l)ΔrG° = ?
ΔfH° (kJ mol-1)-207.091.333.2-285.8
S°(J K-1 mol-1)146.0210.8240.170.0

◦ -186 kJ mol-1
◦ -85.5 kJ mol-1
◦ +50.8 kJ mol-1
◦ +222 kJ mol-1
◦ -151 kJ mol-1
