Answer
(a) Less than.
(b) Less than.
(c) Greater than.
(d) Less than.
(e) Greater than
Work Step by Step
(a) In an exothermic reaction, if we decrease the temperature, the equilibrium shifts to the left, consuming more B.
(b) Adding reactants shifts the equilibrium to the left, consuming more B.
(c) Adding products shifts the equilibrium to the right, producing more B.
(d) Removing products shifts the equilibrium to the left, consuming more B.
(e) The reactants have the least amount of moles of gases, so they are favores when we decrease the volume, producing more B.
