Initially 0.0259 M of SO2 (g) and 0.0200 M of O2 (g) are prepared at 1273 C in a reaction vessel with no SO3 (g) added initially.
They react to form at equilibrium 0.0162 M of SO3 (g)
Explain what are the equilibrium values of all three components?
The gases react as
2 SO2 (g) + O2 (g) <==> 2 SO3 (g)
