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