Question 1

A reaction that proceeds simultaneously in both directions

Answer 1

Reversible reaction

Question 2

When the rates of the forward reaction and the reverse reaction are the same

Answer 2

The system is in equilibrium

Question 3

equilibria in which all reactants and products are in the same phase

Answer 3

Homogenous equilibria

Question 4

equilibria in which all reactants and products are not in the same phase

Answer 4

Heterogenous equilibria

Question 5

Can make qualitative predictions about what happens to an equilibrium mixture when a change is made

Answer 5

Factors that affect chemical equilibrium

Question 6

When stress is applied to a system at equilibrium, the system will respond by shifting in the direction the minimizes the effect of the stress

Answer 6

Le Châtelier’s Principle

Question 7

Refers to a disturbance of the system at equilibrium

Answer 7

stress

Question 8

addition of a reactant or product

Answer 8

Type of disturbance

Question 9

removal of reactant of a reactant or product

Answer 9

Type of disturbance

Question 10

change in volume of the system, resulting in a change in concentration or partial pressure of the reactants and products

Answer 10

Type of disturbance

Question 11

change in temperature

Answer 11

Type of disturbance

Question 12

refers to the favoring of either the forward or reverse reaction such that stress is partially offset as the system re-establishes equilibrium

Answer 12

Shifting
