Consider the reaction represented by the following equation: 2SO2 + O2 ⇌ 2SO3
A. decrease in the concentration of SO2
B. have no effect on the reaction
C. shift the equilibrium position to the left
D. shift the equilibrium position to the right
Correct Answer:
Option C – shift the equilibrium position to the left
Explanation
decrease in pressure favors the side with higher volume thus the equilibrium position will shift to the left
