Reversible reactions
Reversible reactions
Reactions proceeding in both forward and reverse directions
Dynamic equilibrium
Dynamic equilibrium
Forward and reverse reaction rates are equal
Concentrations at equilibrium
Concentrations at equilibrium
Remain constant
Must concentrations be equal at equilibrium?
Must concentrations be equal at equilibrium?
No, constant but not necessarily equal
Closed system
Closed system
System where no substances can enter or leave
System required for dynamic equilibrium
System required for dynamic equilibrium
Closed system
Reactions at equilibrium
Reactions at equilibrium
Continue simultaneously
Forward vs reverse rate at equilibrium
Forward vs reverse rate at equilibrium
Same rate
Why 'dynamic' in dynamic equilibrium?
Why 'dynamic' in dynamic equilibrium?
Both reactions continue to occur
