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

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.

Did you know?

The Centers for Disease Control and Prevention has released reports detailing the deaths of infants (younger than 1 year of age) who died after being given cold and cough medications. This underscores the importance of educating parents that children younger than 2 years of age should never be given over-the-counter cold and cough medications without consulting their physicians.
