11 - equilibrium 2

Question 1

what is a homogeneous reaction?

Answer 1

all reactants and products are in the same phase e.g. all gases, all aqueous, etc.

Question 2

what is the only factor to affect the equilibrium constant?

Answer 2

temperature

Question 3

what is a heterogeneous reaction?

Answer 3

a reaction where at least one of the reactants and/or products is in a different phase to others

Question 4

how do we calculate partial pressure?

Answer 4

mole fraction x total pressure
mole fraction of A = number of moles of A/total number of moles of gas

Question 5

what phase is not included in Kp (or Kc)?

Answer 5

solids

Question 6

what effect does temperature have on Kp and Kc?

Answer 6

exothermic reaction - increased temp = decreased K
endothermic reaction - increased temp = increased K

Question 7

what happens to equilibrium when temperature is changed?

Answer 7

increased temp shifts equilibrium in endothermic direction

Question 8

NOTE TO SELF

Answer 8

haven’t made notes on p16-17 as feel like it is common sense however read through/make more fc is necessary!!
