Consider the reaction: 2H 2 S (g)+ 3O 2 (g)⇔ 2SO 2 (g)+ 2H 2 O (g)to answer the following questions.
-Refer to the reaction shown above. Which of the following will shift the equilibrium to the left?

Decreasing the pressure will shift the equilibrium to the side with fewer moles of gas, which is the left side in this case. Adding sulfur dioxide will also shift the equilibrium to the left because it is a reactant in the forward reaction.

Consider the Reaction: 2H2S (G)+ 3O2 (G)⇔ 2SO2 (G)+ 2H2O

Consider the Reaction: 2H₂S (G)+ 3O₂ (G)⇔ 2SO₂ (G)+ 2H₂O
