Equilibrium Flashcards
1
Q
A closed system
A
A system in which mass is conserved inside the system but energy can enter or leave the system freely
2
Q
An open system
A
A system in which both energy and matter can be exchanged between the system and its surroundings
3
Q
Le Chatelier’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’
4
Q
Reversible Reaction
A
A reaction in which the products can be converted back into reactents
5
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
