A. Equilibrium shifts left
B. Equilibrium shifts right
C. No effect
D. Increases K value
Answer: Equilibrium shifts right
For the reaction 2SO2(g) + O2(g) ⇌ 2SO3(g), if the concentration of SO2 is decreased, what happens?
Additional Information: Decreasing SO2 concentration shifts equilibrium to produce more SO2, favoring the right side.
