Question 1

Estimate ΔrG° for the following reaction at 775 K.

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

◦ -110 kJ mol-1
◦ +17 kJ mol-1
◦ -625 kJ mol-1
◦ +321 kJ mol-1
◦ -181 kJ mol-1

Question 2

Determine ΔrG° at 298 K using the following information:

FeO(s) + CO(g) → Fe(s) + CO2(g)ΔrH°= -11.0 kJ mol-1; ΔrS°= -17.4 J K-1 mol-1

◦ -5.8 kJ mol-1
◦ +191.0 kJ mol-1
◦ +89.5 kJ mol-1
◦ +1.6 kJ mol-1
◦ -6.4 kJ mol-1
