3. Equilibrium

Question 1

What is the relationship between d(G) and K

Answer 1

D(G) = -RTlnK

Question 2

How do you convert pressures to concentrations?

Answer 2

P(A) = [A]RT

Question 3

What does a large value of Kc mean

Answer 3

The eqm is on the product side

Question 4

What does a small value of Kc mean

Answer 4

The equilibrium is on the reactant side

Question 5

If Qc>Kc…?

Answer 5

reactants will tend to form

Question 6

If Qc

Answer 6

Products will tend to form

Question 7

What is the general relationship between Kp and Kc?

Answer 7

Kp = Kc(RT)^d(n)

Question 8

What is heterogenous equilibrium?

Answer 8

Components exist in different physical forms (one or more components are of different phases than the others)

Question 9

What is Le chatelier’s principle?

Answer 9

If an outside influence upsets an equilibrium, the system undergoes a change in a direction that counteracts the disturbing influence and if possible, returns the system to equilibrium.

Question 10

How can the K value at a specified temperature be calculated if the value of K at another temperature is known?

Answer 10

The Van’t hoff equation

.lnK(T1)-lnK(T2) = d(H)/R(1/T1- 1/T2)

Question 11

What is the equation for oxygen transport?

Answer 11

Hb4(aq) + 4O2(aq) <=>Hb4O8
