Consider the equation 2SO 2 (g)+ O 2 (g)⇔ 2SO 3 (g). Increasing the pressure will ________.

Increasing the pressure will shift the reaction to the side with fewer moles of gas. In this case, the right side has fewer moles (2 moles of SO3) compared to the left side (3 moles of gases), so the reaction shifts to the right.
