Equilibria Flashcards
What is dynamic equilibrium
When the forward and backward rate of reaction is the same and remains at constant rate
What are the conditions for dynamic equilibrium
Closed system
What will reversible reactions lead to
Dynamic equilibrium
What is Le Chateliers Principle
When a system is subject to change the system will alter to lessen the effects of that change
What does increasing temp favour
Endothermic reaction
What does decreasing temperature favour
Exothermic reaction
What will increasing pressure favour
The side with the less molecules
What will decreasing pressure favour
The side of the reaction with the most moles
What will increasing concentration favour
Side that produces the products
What will decreasing concentration favour
Favour the reaction that reforms the reactants
What effect does catalyst have on equilibrium
Has no effect as it affects the forward and backwards equally
What is equilibrium constant , kc
Indicates the position of equilibrium
What doesn’t affect Kc
2 points
Concentration
Catalysts
What affects Kc and why
Temperature
As equilibrium position changes so different concentrations
