An equilibrium mixture of the following reaction was found to have [SO3] = 0.391 M and [O2] = 0.125 M at 600 °C. What is the concentration of SO2?

Question

2 SO2 (g) + O2 (g) ====== 2 SO3 (g)
Keq = 4.34 at 600 °C

Answer 1

Kc = (SO3)^2/(SO2)^2(O2)
You K, SO3 and O2. Solve for the only unknown there, SO2.

Answer 2
