Question 1

Consider the reaction:
3 N2(g) + 2 O3(g) → 6 NO(g)
ΔfH° (kJ/mol) 0.00 142.26 90.37  
S°  (J/mol K)  191.5  237.7  210.6  

What is ΔrG° for this reaction in kJ at 500 K?
◦ 93 kJ
◦ 151 kJ
◦ 365 kJ
◦ -1.00 × 105 kJ
◦ 441 kJ

Question 2

Consider the reaction: N2O4(g) → 2 NO2(g)

Keq = 0.1134 at 20 °C ΔrH°= 58.03 kJ/mol

What is ΔrG° for this reaction at 20 °C?
◦ 0.36 kJ/mol
◦ -5.4 kJ /mol
◦ 4.9 kJ/mol
◦ 5.3 kJ/mol
◦ 5.4 kJ/mol
