When particles have Effective collisions (EC), particles (reactants) rearrange into new groupings (products) and we say there is a chemical reaction (rxn).
Question: THEN WHAT?
Two possibilities:
Irreversible rxn :
Reversible rxn:
Forward reaction:
Backward or reverse reaction:
Virtually All Chemical Reactions are ____________________
?
Then why are irreversible not reversible?
Big condition needed for a reaction to be reversible: Closed system -
Equilibrium
Your definition:
Definition of Equilibrium:
Big Take Aways for Equilibrium:
Rate of forward reaction = Rate of backward reaction
Time independent, [ ] of each species are constant (but don't have to be
same
).
? What happens if you disturb Equilibrium?
LeChatelier's Principle says:
Big Take Away: Can't get there (changed system), so create new one
