Question 1

Calculate ΔrG° at 298 K using the following information:

4HNO3(g) + 5N2H4(l) → 7N2(g) + 12H2O(l)ΔrG° = ?
ΔfH° (kJ mol-1)-133.950.6-285.8
S°(J K-1 mol-1)266.9121.2191.670.0

◦ +3.90 × 103 kJ mol-1
◦ -3.30 × 103 kJ mol-1
◦ -3.15 × 103 kJ mol-1
◦ +4.90 × 103 kJ mol-1
◦ -2.04 × 103 kJ mol-1

Question 2

Calculate ΔrG° at 298 K using the following information:

2H2S(g) + 3O2(g) → 2SO2(g) + 2H2O(g)ΔrG° = ?
ΔfH° (kJ mol-1)-20.6-296.8-241.8
S°(J K-1 mol-1)205.8205.2248.2188.8

◦ +108.2 kJ mol-1
◦ -147.1 kJ mol-1
◦ +676.2 kJ mol-1
◦ -466.1 kJ mol-1
