b. The equilibrium shifts in the direction of reactants.
c. The equilibrium shifts in the direction of products.
d. The equilibrium shifts in the direction of reactants.
Work Step by Step
Decreasing the volume of the container causes the equilibrium to shift in the direction of the side with the fewer number of moles of gas per reaction.
a. Reactants: 3 moles; Products: 2 moles. Shifts in the direction of products.
b. Reactants: 2 moles; Products: 3 moles. Shifts in the direction of reactants.
c. Reactants: 6 moles; Products: 0 mole. Shifts in the direction of products.
d. Reactants: 4 moles; Products: 5 moles. Shifts in the direction of reactants.
