Question 1

Consider the reaction:
  N2(g) + 3 X2(g) → 2 NX3(g)
fH° (kJ/mol) 0.0 0.0 43  
S° (J/(mol K)) 192 210  172

What is Keq for this reaction at 591 K?
◦ 2.3 × 1017
◦ 4.3 × 10-18
◦ 1.04
◦ 0.96
◦ 132

Question 2

Consider the reaction:  AB(g) → A(g) + B(g)  

(Keq = 0.729 at 20 °C ΔrH° = 45.9 kJ/mol)

What is Keq for this reaction at 425 K?
◦ 476
◦ 0.733
◦ 0.725
◦ 254
◦ 2.10 × 10-3
