Equilibrium Flashcards
1
Q
Keq<1
A
(+) G
Reactants lower in energy, more stable
Reactants favoured
2
Q
Keq>1
A
(-) G
Products are lower in energy
Products favoured
3
Q
Keq=1
A
Ratio of products /reactants at equilbrium are equil
4
Q
Q< Keq
A
More reactants
Forward reactions occurs
5
Q
Q>Keq
A
More products
Reverse reaction occurs
6
Q
Q=Keq
A
At equilibrium
7
Q
IP< Ksp
A
MIxture is unsaturated
Forward reaction proceeds
No precipitation
8
Q
IP= Ksp
A
Mixture is satruated
At equilibrium
No ppt
9
Q
IP> Ksp
A
Mixture is super saturated
Reverse reaction occurs
Ppt occurs
10
Q
Ka<1
A
Weak acid
11
Q
Kb <1
A
Weak base
12
Q
Ka>1
A
Low pKa= strong acid
Low Kb
13
Q
Kb>1
A
Strong base= low Ka
14
Q
Equivalence Point
A
Equal moles of acid and base in a titration
15
Q
Half Equivalence POint
A
Equal numbers o facid and CB
Half of the acid/base hase been used up
Pk= pH
