consider the reaction represented by the following equation: 2SO\(_2\) + O\(_2\)  ⇌ 2SO\(_3\) 

A decrease in the pressure of the reaction would

A.

decrease in the concentration of SO\(_2\)

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 is C

Decrease in pressure favors the side with higher volume thus the equilibrium position will shift to the left
