Answer
a. The equilibrium shifts in the direction of the products.
b. The equilibrium shifts in the direction of the reactants.
c. The equilibrium shifts in the direction of the products.
d. The equilibrium shifts in the direction of the products.
e. Does not affect the equilibrium.
Work Step by Step
a. The heat is on the products side, which means that the reaction is exothermic. Therefore, a decrease in temperature will shift the equilibrium in the direction of the products.
b. Adding more product will cause a shift in the direction of the reactants.
c. Removing some product will cause a shift in the direction of the products.
d. Adding more reactant will cause a shift in the direction of the products.
e. Decreasing the volume of the container shifts the equilibrium to the side that has a lower number of moles of gas.
Reactants side: 2 moles of gas.
Products side: 2 moles of gas.
The equilibrium will not be affected by this change.
