Equilibrium Flashcards
Reaction keeps going until one reactant runs out and there is no more reaction possible
“gone to completion”
Q is the symbol for…
Reaction quotient
Way to understand the composition of your reactant mixture
Reaction quotient Q
[ ] represent what?
Concentration
In a reaction quotient, what do the concentration terms need to be raised to?
The power of their co efficients
If the initial concentration of N2O4 was 1 mol, and its gone down to 0.8 mols, that means that … mols must have reacted
0.2 mols
If 0.2 mols of the N2O4 has reacted, the stoichiometry balanced equation tells us we must have made … mols of the NO2, because everytime one N2O4 reacts, we make 2 NO2s
0.4 mols
When a reaction stops increasingly suddenly but there are still reactant molecules this means what?
The reaction has not gone to completion
The reaction is going both ways at the same time
At equilibrium
Reactants are turning into products just as quickly as other products are turning into reactants
Dynamic equilibrium
Stuff is still happening, but there is no overall changes in concentrations
Dynamic equilibrium
The general way to describe what you have in your reaction mixture
Reaction quotient
Way of describing what you have in your reaction mixture when it reaches equilibrium
Equilibrium constant
The value of the equilibriu constant has no…
