Answer
a. The equilibrium shifts in the direction of products.
b. The equilibrium does not change.
c. The equilibrium shifts in the direction of reactants.
d. The equilibrium shifts in the direction of products.
Work Step by Step
Increasing the volume of the container causes the equilibrium to shift in the direction of the side with the greater number of moles of gas per reaction.
a. Reactants: 2 moles; Products: 4 moles. Shifts in the direction of products.
b. Reactants: 2 moles; Products: 2 moles. Does not affect the equilibrium.
c. Reactants: 3 moles; Products: 2 moles. Shifts in the direction of reactants.
d. Reactants: 7 moles; Products: 8 moles. Shifts in the direction of products.
