consider the reaction represented by the following equation: 2SO\(_2\) + O\(_2\) ⇌ 2SO\(_3\)
A decrease in the pressure of the reaction would
decrease in the concentration of SO\(_2\)
have no effect on the reaction
shift the equilibrium position to the left
shift the equilibrium position to the right
Explication
decrease in pressure favors the side with higher volume thus the equilibrium position will shift to the left
