Chemical Equilibria Flashcards
State the Le Chatelier’s Principle
It states that when a stress is applied to a system at equilibrium, the position of equilibrium will shift so as to minimise the stress.
Define reversible reaction
It is a reaction that can proceed in both the forward and reverse directions. The reaction mixture contains quantites of all reaction species in the system.
Define dynamic equilibrium
It occurs in a reversible system where the rate of forward and reverse reactions are the same. There is no net change in the concentration of the reactants and products
When can dynamic equilibrium occur?
Only when it is a closed system at constant temperature.
Standard free energy change can be used during what kind of change
It is for the complete transformation of pure reactants into pure products.
