a. The equilibrium shifts in the direction of the reactants. b. The equilibrium shifts in the direction of the products. c. The equilibrium shifts in the direction of the reactants. d. The equilibrium shifts in the direction of the products. e. The equilibrium shifts in the direction of the reactants.

a. Removing some reactant will cause a shift in the direction of the reactants. b. 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. c. Adding more product will cause a shift in the direction of the reactants. d. Adding more reactant will cause a shift in the direction of the products. e. Increasing the volume of the container shifts the equilibrium to the side that has a greater number of moles of gas. Reactants side: 4 moles of gas. Products side: 2 moles of gas. The equilibrium will shift in the direction of the reactants side.
