5.1.2: How Far?

Question 1

Mole fraction

Answer 1

Mole fraction of A = n(A)/n(all gases)

Question 2

Partial pressure

Answer 2

Partial pressure = mole fraction x total pressure

Question 3

Kp

Answer 3

!!!ONLY FOR THE GASES IN THE EQUATION!!!
Kp = p(Products)/ p(Reactants)

Question 4

RICE TABLE

Answer 4

Ratio
Initial mol
Change in mol
Equilibrium mol
Total moles
Mole fraction
Partial pressure

Question 5

What affects Kp

Answer 5

Only temperature affects Kp
If forward reaction endothermic and temperature increases, Kp increases
If forward reaction exothermic and temperature increases, Kp decreases

Pressure does not affect Kp
Concentration does not affect Kp

Question 6

What affects Kc

Answer 6

Only temperature affects Kc
If forward reaction endothermic and temperature increases, Kc increases
If forward reaction exothermic and temperature increases, Kc decreases

Pressure does not affect Kc
Concentration does not affect Kc
