Chemical Equillibria Flashcards
(7 cards)
What does dynamic state mean
Forward and reverse reactions are ongoing
What makes an equilibrium
Rate of forward and reverse reactions are equal
Concentrations of the reactants and products remain constant
Le chatelier’s principle
If a factor affecting the position of equilibrium is altered, the position of equilibrium shifts to oppose the effect of the change
What happens to equilibrium if temperature is increased
Equilibrium shifts to decrease the temperature
Equilibrium shifts in the endothermic direction
What happens to equilibrium when conc of one substance is increased
Equilibrium shifts to decrease amount of substance
Equilibrium shifts to opposite side
What happens to equilibrium when pressure is increased
Equilibrium shifts to decrease the pressure
Equilibrium shifts in the direction of the fewest molecules
What effect does a catalyst have on position of equilibrium
No change on position of equilibrium is
(Rate of forwards and backwards reactions increases equally)
Equilibrium is reached faster
