le chatelier

when u change an eq

the eq will undo ur change

which changes have speicifc states it only works with

change amtn reac/prod onluy work with gas and aq not solid or liquid

change p/v only work with gas, not aq s or l

change amnt water only change aq

add amtn prod/reac

only for gas and aq

eq shifts to side with less prod/reac

remove prod/reac

only for gas and aq

eq shifts to side wityh that prod/reac

incresae temp

favor endo side (side with more energy, the side that absorbs)

decrese temp

favor exo side (side with less energy, the side that releases heat)

how does temp impact keq

if temp made rxn shift right, bigger keq

if temp made rxn shift left, smaller keq

increawse P

which means v decrease

shifts to side with less moles of gas

decresase Pressure

which means increase volume

shifts to side with more moles of gas

for inert gases, why would lechatelier want to change/do the opp action

cuz partial pressure of gas prod/reac

not concerned about pressures of anything else

cuz p prod/reac is the amnt collisions of prod/reac which is how rxn runs

add inert gas that isn’t at constant p

P changes and V doesn’t

no shift

add inert gas under constant P

This menas volume change (P doens’t)

more volume means shift to side with more moles of gas

less volume means shift to side with less moles of gas

if you add H2o

for just aq,

less concentration of aq prod/reac

shift to side with more mol aq

if you remove/h2o evaporates

only for aq

concentration aq higher

shift to side with less moles aq
