Exam 4 ch 15 Flashcards
(11 cards)
1
Q
eqillibrium expression
A
Homogenous: All same state, only aq invluded
Heterogeneous: different states, solids and liquids not included
2
Q
Delta G and K
A
^G = -RTlnK
R = 8.314 J/molK
3
Q
K forward and reverse
A
Forward: pro/rea = number
reverse = rea/pro = 1/number INVERSE
4
Q
Large vs small K
A
Large: Product favored, spontaneous
Small: reactant favored, non spontaneous
5
Q
Multiply reaction
A
Raise K to that number
6
Q
Add reactions
A
Multiply Ks
7
Q
Reaction quotient (Q)
A
-Like equillibrium constant but current concentrations
8
Q
Q > K
A
Rxn proceeds towards reactants
Need more reactants
9
Q
Q < K
A
Rxn proceeds towards products
Need more product
10
Q
Q = K
A
Rxn at equillibrium
11
Q
LaChatliers principle
A
-If a system is at equilibrium, the system will shift in a direction that reduces stress
