C13 Equilibrium Flashcards
What is a reversible reaction?
The reactants turn in to products and the products turn in to reactants
What is dynamic equilibrium?
The point in a reversible reaction when the rate of forwards and reverse reactions are the same
What three reaction conditions can be changed?
concentration
temperature
pressure
What is Le Chatelier’s principle?
The position of equilibrium will shift to oppose external changes
What is the effect of increasing the concentration of reactants on a reaction at dynamic equilibrium?
Favours the forward reaction
What is the effect of decreasing the concentration of products on a reaction at dynamic equilibrium?
Favours the forward reaction
What is the effect of increasing pressure on a reaction at dynamic equilibrium?
Favours the reaction that leads to the fewest molecules
What is the effect of decreasing pressure on a reaction at dynamic equilibrium?
Favours the reaction that leads to the most molecules
What is the effect of increasing temperature on a reaction at dynamic equilibrium?
Favours endothermic reaction
What is the effect of decreasing temperature on a reaction at dynamic equilibrium?
Favours the exothermic reaction
