Chapter 13: Equilibria Flashcards
1
Q
K > 1
A
more products
2
Q
K < 1
A
more reactants
3
Q
K = 1
A
equal reactants and products
4
Q
Q < K
A
rxn goes to the right
5
Q
Q = K
A
equilibrium
6
Q
Q > K
A
rxn goes to the left
7
Q
neglect x if…
A
[ ]i / K > 400
8
Q
change in [ ] changes…
A
Q, but NOT K
9
Q
changing the volume of a rxn only shifts equilibrium if…
A
changing in moles is NOT equal to 0
10
Q
increase in volume
A
-decreases pressure
-rxn shifts to the side with more moles
11
Q
decrease in volume
A
-increases pressure
-rxn shifts to the side with less moles
12
Q
heat in an endothermic rxn
A
added to reactant side
13
Q
heat in an exothermic rxn
A
added to product side
14
Q
effect of heat on endo rxn
A
-adding heat = shift to the right
-removing heat = shift to the left
15
Q
effect of heat on exo rxn
A
-adding heat = shift to the left
-removing heat = shift to the right
