Chemical Equilibrium Flashcards
1
Q
Closed system
A
A system in which mass is conserved inside the system but energy can enter or leave the system freely
2
Q
Open system
A
A system in which both energy and matter can be exchanged between the system and its surroundings
3
Q
Dynamic chemical equilibrium
A
Refers to 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
4
Q
Le Châtelier’s Principle
A
‘ When an external stress (change in pressure, temperature or concentration) is applied to a system in dynamic chemical equilibrium, the equilibrium point will change in such a way as to counteract the stress’
