Question

Consider this reaction: 2SO2(g) + O2(g) = 2SO3(g) + heat. What will happen if more oxygen is added to the reaction mixture?

A.) The equilibrium will shift toward the products.
B.) The equilibrium will shift toward the reactants.
C.) Keq will increase.
D.) Keq will decrease.
E.) There will be no shift in equilibrium.

Answer 1

Le Chatlier's principle

adding O2 will shift the reaction to the right since O2 is a reactant

Answer 2

Thank you :)
