Question 1

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

NO(g) + O(g) → NO2(g)ΔrG° = ?
2O3(g) → 3O2(g)ΔrG° = +489.6 kJ mol-1
O2(g) → 2O(g)ΔrG° = +463.4 kJ mol-1
NO(g) + O3(g) → NO2(g) + O2(g)ΔrG° = - 199.5 kJ mol-1

◦ -225.7 kJ mol-1
◦ -1152.5 kJ mol-1
◦ -676.0 kJ mol-1
◦ +753.5 kJ mol-1
◦ +277.0 kJ mol-1

Question 2

Calculate ΔrG at 298 K under the conditions shown below for the following reaction:

SO3(g) + H2O(g) → H2SO4(l)ΔrG°= -90.5 kJ mol-1

P(SO3) = 0.20 atm, P(H2O) = 0.88 atm

◦ +51.4 kJ mol-1
◦ -30.4 kJ mol-1
◦ +15.9 kJ mol-1
◦ -90.5 kJ mol-1
◦ -86.2 kJ mol-1
