Equilibrium Flashcards
What is dynamic equilibrium
I’m some reversible reactions , forward and backward reactions largely occur in the same conditions and at same rate
Dynamic equilibrium means what
There is no overall change in amount of products and reactants even tho reactions are ongoing
Where can dynamic equilibrium only take place
In a closed system otherwise products Escape
What is position of equilibrium influenced by
Temperature
Concentration
What does adding a catalyst do to equilibrium
Speeds up time taken to reach equilibrium but doesn’t change position
What effect does temp have in equilibrium
Shifts it In direction that takes in heat
What effect does concentration have on equilibrium
Shifts it in direction that produces less of that substance
What effect does pressure have on equilibrium
Shifts it in direction that produces less gas
What do exothermic reactions do
Give out heat
What do endothermic reactions do
Take in heat
If the temp is increased what happens
Equilibrium shifts to decrease temp
Shifts in endothermic direction
If temp is decreased
Equilibrium shifts to increase temp
Shifts in exothermic direction
What is equilibrium
When the forward and reverse reactions occur at equal rates
