Question 1

heterogeneous vs homogeneous equilibria

Answer 1

het:
(Species have) different states/phases
hom:
(Species have) same states/phases

Question 2

calculating Kc

Answer 2

the ratio of the equilibrium concentrations of products over the equilibrium concentrations of reactants each raised to the power of their stoichiometric coefficients
in heterogeneous eq with solids, don’t count the solid as not a concentration in eq mixture.

Question 3

calculating Kp

Answer 3

same as Kc, but instead of concentration, use partial pressure
therefore only consider gasses for heterogeneous eq

Question 4

define mole fraction

Answer 4

the proportion a molecule accounts for the total moles present
calculated by moles of substance/ total moles

Question 5

define partial pressure

Answer 5

within a gaseous system each gas has a partial pressure, a fraction of the total pressure- found by mole fraction * total pressure.

Question 6

increasing/decreasing temp on exo/endothermic equilibria

Answer 6

changes the concentrations of reactants so Kc/Kp changes
