Answer 6

Base ionization constant

Question 7

Kf

Answer 7

Formation constant of complexes

Question 8

Kd

Answer 8

Dissociation constant in complex action reactions

Question 9

What types of molecules are included in an equilibrium expression

Answer 9

Gasses and aqueous solutions

Question 10

Kc’

Answer 10

The inverse of Kc

1/Kc

Question 11

K overall

Answer 11

K1 X K2

Question 12

How is K overall found

Answer 12

By adding the first and second chemical reactions and writing the equilibrium constant for the new equation

Question 13

A very small K value indicates

Answer 13

Very little product formation and almost no visible reaction at equilibrium

Question 14

A large value indicates…

Answer 14

The amount of products present at equilibrium is much greater than that of the reactants

Question 15

K=1 indicates that

Answer 15

The equilibrium mixture contains approximately equal amounts of reactants and products

Question 16

Spontaneous reaction

Answer 16

Products are formed when reactants are mixed without additional assistance

Question 17

In a spontaneous reaction the equilibrium constant is generally

Answer 17

Greater than 1

Question 18

In a non spontaneous reaction the equilibrium constant is generally

Answer 18

Less than 1

Question 19

Q

Answer 19

Reaction quotient

Question 20

Reaction quotient is defined as

Answer 20

The number obtained by entering all of the required concentrations into the equilibrium expression and calculations the result

Question 21

Q is equal to

Answer 21

The numerical value of Kc when a reaction is not at equilibrium

Question 22

If Q does not change with time then

Answer 22

The reaction is in a state of equilibrium and Q=Kc

Question 23

If Q=Kc then

Answer 23

The reaction is at a state of equilibrium

Question 24

If Q<Kc

Answer 24

The reaction will move in the forward direction (to the right) to reach equilibrium

Question 25

If Q>Kc then

Answer 25

The reaction moves in the reverse direction (to the left) to reach equilibrium
