Approaching Chemical Equilibrium (15.2.1)

Question 1

• The equilibrium constant (Kp) indicates whether a particular equilibrium favors reactants or products and the two principles that determine the equilibrium
constant are the enthalpy of reaction (∆Hrxn) and entropy.

Answer 1

• The equilibrium constant (Kp) indicates whether a particular equilibrium favors reactants or products and the two principles that determine the equilibrium
constant are the enthalpy of reaction (∆Hrxn) and entropy.

Question 2

• A Kp value greater than one indicates that the products are favored at equilibrium, whereas a Kp value less than one indicates that the reactants are favored at equilibrium.

Answer 2

• A Kp value greater than one indicates that the products are favored at equilibrium, whereas a Kp value less than one indicates that the reactants are favored at
equilibrium.

Question 3

• For any exothermic reaction in which the products are more ordered, the equilibrium will favor products at low temperatures and reactants at high temperatures.

Answer 3

• For any exothermic reaction in which the products are more ordered, the equilibrium will favor products at low temperatures and reactants at high temperatures.
