2 SO3 (g) + Heat <> 2 SO2 (g) + O2 (g) For the above reaction, what will happen to the concentration of SO2 if the pressure is increased? Explain your answer

The concentration of SO₂ will decreases

Explanation:

As you can see in the reaction

2 moles of gas ⇆ 3 moles of gas

Based on Le Châtelier's principle, a change doing in a system will produce that the system reacts in order to counteract the change made.

If the pressure is increased, the system will shift to the left in order to produce less moles of gas and decrease, thus, the pressure.

As the system shift to the left, the concentration of SO₂ will decreases
