Question

Write your answers and show your calculations on a separate sheet of paper for partial or full credit. No need to rewrite the question, just label it properly.  (Keep questions in sequential order.)

Consider the following equilibrium reaction:

                      SO2(g) + NO2(g)  ⇌ NO(g) + SO3(g)            Kp = 2.6 x 10-2  at T = 350 K

0.850 atm of NO(g) and 0.850 atm of SO3(g) are placed in a 2.10 L flask and allowed to reach equilibrium.

a) Write the Kp expression for this reaction.

b) Determine the equilibrium partial pressures of each reactant and product.  

c) Once the reaction is at equilibrium and the volume of the container is decreased to 1.50 L, in which direction if any, will the reaction proceed? Explain your answer.
