Answer
(a) The equilibrium shifts to the right.
(b) The equilibrium shifts to the left.
(c) The equilibrium shifts to the right.
(d) The equilibrium shifts to the left.
(e) The equilibrium is not affected.
Work Step by Step
(a) The reaction is endothermic ($\Delta$H greater than 0), therefore, increasing temperature shifts the equilibrium to the right.
(b) Adding products favors reactants.
(c) Removing products favors products.
(d) If there are gases in both sides of the reaction, the one with the least amount of moles of gases will be favored after increasing the pressure.
(e) Catalysts do not affect equilibrium.
