Answer
a. The equilibrium shifts in the direction of reactants.
b. The equilibrium shifts in the direction of products.
c. The equilibrium is not affected.
d. The equilibrium shifts in the direction of products.
Work Step by Step
a. Since the heat is on the products side of the reaction, when the temperature increases, the equilibrium shifts in the direction of reactants.
b. The reactants side has a total of 2 moles of gas, and the products side has 1 mole of gas. Therefore, decreasing the volume of the container shifts the equilibrium in the direction of products.
c. Adding a catalyst will not affect the equilibrium.
d. Adding some reactant will shift the equilibrium in the direction of products.
