What is dynamic equilibrium?
Exists in a closed system when the rate of the forward reaction equals the rate of the backward reaction, and conc of reactants and products do not change
Outline le Chatelier’s principle
States when any change is made to conditions of a dynamic equilibrium, POE moves in the direction that minimises the change
Will adding or removing a catalyst cause any change to the POE?
No as it would just increase or decrease the rate of both reactions
What would happen when increasing temperature of a dynamic equilibrium?
POE move in the direction that absorbs heat so endothermic
What would happen when decreasing temperature of a dynamic equilibrium?
POE move in the direction that releases heat so exothermic
What would happen when increasing pressure of a dynamic equilibrium?
POE move in the direction that decreases pressure so direction giving fewer gas molecules
