Question 1

Dynamic equilibrium

Answer 1

Rate of forward reaction = rate of backward reaction. Concentration of reactants and products stay constant

Question 2

Equilibrium constant Kc

Answer 2

Kc = (product of concentration of concentration of reactant) / (product of concentration of concentration of product)

Question 3

Equilibrium constant Kp

Answer 3

same as Kc but with partial pressure
ONLY THE ONES IN GASEOUS STATE

Question 4

Linking entropy with equilibrium

Answer 4

S = RlnK (as K (Kc / Kp) increases, S increasesJ

Question 5

Effects of changing condition on value of Kc or Kp

Answer 5

Larger Kc, greater the amount of products
Temperature: both equilibrium position and value of Kc and Kp will change
Concentration: shift equilibrium position changes, not Kc
Pressure: shift equilibrium position, not Kp
Catalyst: no effect cause both forward and backward rate increases
