a reaction in which the products can react to reform the original reactants
To show a reversiblereaction, two opposing half arrows are used: ⇌
describe dynamic equilibrium
the reactants and products are dynamic/constantly moving
the rate of the forward reaction is the same as the backwards reaction in a closed system and the concentrations of reactants and products are constant
describe a closed system
A closed system is one in which none of the reactants or products escape from the reaction mixture
Describe an open system
In an open system, matter and energy can be lost to the surroundings
Can equilibrium be reached in an open system ?
only when a reaction takes place entirely in solution as a negligible amount of material is lost through evaporation. If the reaction involves gases, equilibrium can only be reached in a closed system
