Exam 3 ch 15 Flashcards
1
Q
Equillibrium
A
Rate forward = rates reverse
2
Q
Equilibrium expression
A
Kc = [C]c[D]d / [A]a[B]b
Products over reactants raised to their stoichiometric coefficients
Pure solids and liquids not included
Units dont matter
3
Q
Delta G
A
^G = -RT lnK
which = ^H-T^S
4
Q
K written normally vs backwards
A
Normal: products / reactants = x
Backwards: Reactants / products = 1/x
5
Q
K if you multiply the reaction
A
Raise it to that number
6
Q
K if you add reactions
A
Multiply Ks together
7
Q
Large K
A
-Product favored
-Spontaneous
- Negative G
8
Q
Small K
A
-Lots of reactant remains at equilibrium
-Reactant favored
-Non spontaneous
-Positive G
