Reversible Reactions Flashcards
What is equilibrium?
When the amounts of reactants and products have reached a balance and stay there
What is a reversible reaction?
A reversible reaction is where the products of a reaction can react with rah other to make the original reactants.
When is equilibrium achieved?
When there is a closed system and a reversible reaction.
What affects the position of equilibrium?
The pressure and temperature around the reaction.
What is the position of equilibrium?
The amount of reactants and products
Does adding a catalyst affect the equilibrium position?
No
Why does the catalyst have no effect in equilibrium reactions position?
Because the catalyst speeds up both reactions
How do you reach equilibrium quicker?
Adding a catalyst
How do you increase the endothermic reaction temperature wise?
The endothermic will increase if you increase temperature
How do you increase the exothermic reaction temperature wise?
By reducing the temperature.
What effect does reducing the temperature have in an equilibrium reaction?
The exothermic increases
The endothermic decreases
What effect does increasing the temperature have in an equilibrium reaction?
The endothermic increases
The exothermic decreases
What effect will raising the pressure have on the equilibrium reaction?
It will make the reaction with a larger volume decrease
It will make the reaction with the lower volume increase
If you lower rthe pressure what effect will it have on the equilibrium reaction?
A lower pressure will encourage the reaction with a larger volume
It will discourage the reaction with a smaller volume
