0
Q
Dynamic equilibrium
A
Forward/reverse process cancel out
1
Q
Static equilibrium
A
Forces in balance, nothing moves
2
Q
Chemical equilibrium
A
Is always dynamic, no net change but molecules never stop reacting
3
Q
Reaction quotient (Q)
A
At any point in a reaction, the value or the equilibrium expression can be calculated
4
Q
K
A
Is related to the free energy of the reaction
5
Q
Le chatelier’s principle
A
Equilibrium will shift (forward/reverse) so as to counter any change
6
Q
Add a reactant (lc)
A
Increases molarity which causes equilibrium to shift towards product
7
Q
Pressure change (lc)
A
Pressure increase ( the reaction vessel made smaller) equilibrium will shift direction that reduces the miles of gas
8
Q
Effect of temp (lc)
A
Find delta h. If negetive shifts left
