Chemical Equilibrium Flashcards
1
Q
Closed system
A
One in which mass is conserved inside the system but energy can enter or leave the system freely
2
Q
Open system
A
One in which both energy and matter can be exchanged between the system and its surroundings
3
Q
Reversible reaction
A
One in which products can be converted back into reactants
4
Q
Dynamic chemical equilibrium
A
A reversible reaction in which the forward and the reverse reactions are taking place at the same rate and hence the concentrations of reactants and products are constant
5
Q
Le Chatelier’s principle
A
When an external stress (change in pressure, temperature or concentration) is applied to a system in dynamic equilibrium, the equilibrium point will change in such a way as to counteract the stress
