A) A sealed container initially contains only 1.0 M gas A and 1.0 M gas B. Upon heating the following reaction takes place: A(g) + 2 B(g) ? C(g)+ 2 D(l). After the reaction comes to equilibrium, the concentration of gas C is 0.25 M. What is the equilibrium constant K_c for this reaction?

B). The decomposition of N₂O₄ into NO₂ has K_p = 2. Some N₂O₄ is placed into an empty container, and the partial pressure of NO₂ at equilibrium is measured to be 0.2 atm. What was the initial pressure in the container prior to decomposition?

C). For the following reaction, find the value of Q and predict the direction of change, given that a 1L flask initially contains 2 moles S₈, 2 moles SF₆, and 2 moles F_2.

1/8 S₈ (s) + 3 F₂ (g) ? SF₆ (g) K_c = 0.425
