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