At 1500K, the oxidation of sulfur dioxide produces sulfur trioxide with an equilibrium constant of K=2.3 x 10 4.
2 SO 2(g) + O 2(g) <--> 2 SO 3(g)
A quantity of sulfur dioxide and oxygen were placed in a 1.0-liter flask and allowed to react at 999K. After an hour the flask contents were analyzed and the following was obtained.
[SO 3] = 0.22M
[SO 2] = 0.55M
[O 2] = 0.27M
Which of the following is correct?

| a. |
The system is at equilibrium
|
|
| b. |
The system has to shift to the right to achieve equilibrium
|
|

Expert Solution
Step 1 Firstly findout the Qc
Qc = [Product] / [ Reactant ]
Qc = [ SO3 ]^2 / [ SO2 ]^2 • [ O2 ]
Qc = (0.22)^2 / (0.55)^2 • ( 0.27 )
Qc = 0.59
