Chapter 13: Equilibrium

Question 1

equilibrium

Answer 1

rate of the forward reaction and rate of the reverse reaction occurring at the same rate
forward and reverse reactions continue to occur: dynamic equilibrium

Question 2

reversible reactions

Answer 2

proceed in forward and reverse directions

Question 3

reaction quotient

Answer 3

describes the status of a reaction
varies as the reaction proceeds towards equilibrium
Qc=Kc
Qc>Kc, reaction will produce more reactants
Qc<Kc, reaction will produce more products

Question 4

equilibrium constant

Answer 4

ratio of the rate constants of each step on the mechanism

Question 5

homogenous equilibria

Answer 5

all reactants and products are in the same phase
occur in solution, either liquid or gas

Question 6

heterogeneous equilibria

Answer 6

reactants and products are in two or more phases

Question 7

coupled equilibria

Answer 7

reverse: reciprocal
doubled: raise to power of two
combine: multiply constants

Question 8

Le Chatelier’s principle

Answer 8

if an equilibrium system is stressed, the system will shift in the direction to restore equilibrium
