AS.2 How Far?

Question 1

Kc

Answer 1

[products] / [reactants]

Power of - coefficient

Question 2

Homogenous equilibrium

Answer 2

All same state

Question 3

Heterogeneous equilibrium

Answer 3

Different states

Solid or liquid excluded from Kc or Kp
Concentrations so high they are constant

Question 4

Calculating moles at equilibrium

Answer 4

[X] = (moles at eq / v)

Question 5

Kp

Answer 5

p (products) / p (reactants)

Question 6

Components of Kp

Answer 6

1) moles at eq
2)mole fractions = x(gas) = n(gas) / total gas
3) partial pressure = p(gas) = x(gas) x partial pressure
4)Kp

Question 7

Kc and Kp temperature

Answer 7

Kp increase/decrease - equilibrium shifts

Temperature increase/decrease - which direction

Forwards reaction is endo/Exo

Question 8

Kc and Kp concentration

Answer 8

No effect
