Equilibrium Flashcards
Find equilibrium constant (Kc)
Product of concentrations of each mole of products/product of concentrations of each mole of reactants
Units of Kc
Depends on the reaction
Dynamic equilibrium
When rate of forwards reaction = rate of backwards reaction in a closed system (concentrations are constant)
Effect of temperature increase on an equilibrium
Equilibrium moves in endothermic direction to counteract the temp change
Rate of reaction also increases
Effect of pressure increase on an equilibrium
Equilibrium shifts to the side with less molecules to counteract the pressure change
Rate of reaction also increases
Effect of adding reactants / products to an equilibrium
Equilibrium shifts to the side opposite from the chemical added, counteracting the change
Effect of adding a catalyst to an equilibrium
Rates of both forward and backward reactions increases
