What is the Q of the reaction?

Question

For the reaction below, the partial pressure of NO₂ is 0.26 bar and the partial pressure of N₂O₄ is 1.0 bar. What is the Q of the reaction? (R = 0.08314 L･bar/mol･K; Kp = 0.25)

2 NO₂ (g) ⇌ N₂O₄ (g)

Answer 1

Q = (N2O4) / (NO2)² = 1.0 / (0.26)² = 1.0 / 0.0676

Q = 14.8
