Equilibria Flashcards
Definition of “dynamic equilibrium”
rates of forward and reverse
reactions are equal
Le Chatelier’s Principle states … ?
equilibrium will move to undo any change imposed by favouring forward or backward reaction until equilibrium is reached again
Does the reaction stop at equilibrium ?
No
Why is it important to reach equilibrium in industry ?
To make more products
Effect of increasing temp ? (2)
- System fights back by trying to lower temperature
2. Temperature reducing reaction is favoured (endothermic reaction)
Effect of Decrease in Temperature ? (2)
- System fights back by trying to raise temperature
2. Temperature increasing reaction is favoured (exothermic)
Effect of Increase in Pressure ? (2)
- System fights back by trying to lower pressure
2. Pressure reducing reaction is favoured (side with less mols of gas )
Effect of Decrease in Pressure ? (2)
- System fights back by trying to raise pressure
2. Pressure increasing reaction is favoured (side with more mols of gas)
Effect of equilibrium when adding of a reactant(2)
Equilibrium tries to remove additional reactant Forward reaction favoured
Effect of equilibrium when Removal of a reactant (2)
Equilibrium tries to replace removed reactant Reverse reaction favoured
Effect of equilibrium when adding of a product(2)
Equilibrium tries to remove additional product Reverse reaction favoured
Effect of equilibrium when Removal of a product(2)
Equilibrium tries to replace removed product Forward reaction favoured
Equilibria can only occur …
Equilibria can only occur in a CLOSED SYSTEM
