# Chapter 13 - Chemical Equilibrium - Questions: 20

#### Answer

a. true b. false; When a product is added to a system at equilibrium at a given temperature, the value of $K$ for the reaction will stay the same when equilibrium is established.

#### Work Step by Step

a. true The added reactant makes the equation unbalanced, so the equilibrium shifts to the side with less, which is the product side to the right, to reestablish equilibrium. b. false; When a product is added to a system at equilibrium at a given temperature, the value of $K$ for the reaction will stay the same when equilibrium is established. The above answer is correct because temperature is the only factor that can change the value of $K$, thus adding more product will not change the $K$ value, it will remain the same.
