Dynamic Equilibrium Flashcards
(11 cards)
What does it mean when a reaction has reached Dynamic Equilibrium
The forward and reverse reactions are occurring at the same rate and the concentration of reactants and products remain constant
Define dynamic
Forward and backwards reactions are happening at the same time
Define equilibrium
Reactants and products present are at constant concentrations (not necessarily equal)
What kind of system is dynamic equilibrium (closed or open)
Closed system
What is meant by the term closed system
Nothing can escape
What 3 factors effect equilibrium
Concentration, pressure and temperature
What did Henri Le Chatleir say about equilibrium
Whatever you do to a reaction at equilibrium the reaction will oppose the change
What would happen to a equilibrium reaction if the temperature increases
The equilibrium would oppose the change to cool the reaction and go in the endothermic direction
What would happen to the equilibrium if pressure was increased
The equilibrium would oppose the change and shift in the direction of lower pressure, the side with lower molecules
What would happen at equilibrium if concentration increased
The equilibrium would oppose the change and shift in the direction of lower concentration
What is the Kc equation
Kc = [C]c [D]d ÷ [A]a [B]b
