Reversible Reactions And Equilibrium Flashcards
Define dynamic equilibrium
When the rates of forward and reverse reactions are equal. Occurs only in a closed system
When dynamic equilibrium has been reached it does not imply that the equilibrium mixture contains 50% reactants and 50% products
.
WHAT group will Ag remove ?
The halogen ions
What happens to the equilibrium when the concentration is increased on right side?
Forward rate of reaction increases
What happens to equilibrium when concentration increase left side ?
Increase backwards reaction
A low temperature favours what type of reaction ?
Exothermic
A high temperature favours what type of reaction?
An endothermic reaction
What effect does a catalyst have on equilibrium?
Equilibrium will be reached faster by the effect of a catalyst but the catalyst does not affect the position of the equilibrium
In a changing pressure equilibrium question it only involves gas particles.
Sound bud
If the reactions says (-ve) it means the forward reaction is?
Exothermic
If the reaction says it’s (+ve) it means the reaction is ?
Endothermic
Increasing the pressure favours a reaction which produces fewer numbers of gas molecules!
.
Decreasing the pressure favours a reaction which produces a greater number of gas molecules
.
WHAT group will Ag remove ?
The halogen ions
What happens to the equilibrium when the concentration is increased on right side?
Forward rate of reaction increases
