How will each of the following changes affect an equilibrium mixture of the 4 ga

Question

How will each of the following changes affect an equilibrium mixture of the 4 gases in this reaction?
1) The volume of the reaction vessel is doubled.

a) Keq will not change and the equilibrium will shift toward the reactant

b) Keq will not change and the equillibrium will shift toward the product

2) A catalyst is added to the reaction mixture.

a) Equillibrium will not shift

b) Keq will increase and the equilibrium will shift towards the product.

Consider the following equilibrium for which 2 Cl2(g) + 2 H2O(g) How will each of the following changes affect an equilibrium mixture of the 4 gases in this reaction? 1) The volume of the reaction vessel is doubled. a) Keq will not change and the equilibrium will shift toward the reactant b) Keq will not change and the equillibrium will shift toward the product 2) A catalyst is added to the reaction mixture. a) Equillibrium will not shift b) Keq will increase and the equilibrium will shift towards the product. triangle H = -114.44: 4 HCl(g) + O2(g)
