TOPIC 11: Equilibrium 2

Question 1

Kc units

Answer 1

Write all units of concentrations and cancel

Question 2

Kc Equilibrium concentration calculation

Answer 2

Moles and ratios
(Product increase, reactants decrease)
I Initial
C Change
E Equilibrium

Question 3

Total pressure

Answer 3

Sum of all pressures of individual gases (partial pressures)

Question 4

Mole fraction

Answer 4

Proportion of a gas in a gas mixture
= number of moles of gas / total number of moles of gas

Question 5

Partial pressure p(X)

Answer 5

Mole fraction of gas x total pressure in mixture

Question 6

Kp Equilibrium constant

Answer 6

(homogeneous)
= ((pG)^g x (pH)^h)/((pE)^e x (pF)^f)

For units: write in equation and cancel

(heterogeneous)
Only include gases

Question 7

Effects on Kp

Answer 7

Temperature: changing causes equilibrium to shift right, increases

Pressure: unaffected

Catalyst: non
