C7-Chemical Equilibrium Flashcards
(5 cards)
1
Q
Dynamic equilibrium
A
A chemical state achieved when:
- rate of forward reaction=rate of backward reaction
- quantity of reactants and products remains constant in a closed system
2
Q
Le Chatelier’s principle
A
If a change is applied to a system in eq.,
eq. shifts in the direction
that counteracts effects of change,
forming new eq.
3
Q
What are Kc affected and not affected by?
A
Affected by temperature.
Not affected by changes in concentration, pressure, surface area, catalyst.
4
Q
Homogenous condition
A
Reactants and products coexist in same physical state at equilibrium.
5
Q
Heterogenous condition
Take liquid or gas only for Kc or Kp
A
Reactants and products in different physical states at equilibrium
