LE CHATELIER'S PRINCIPLE
S TRESS
S HIFT
WHY?
increase concentration of away from substance
extra concentration
a substance
needs to be used up
need to produce more of
substance to make up for
what was removed
for gas: pressure increase
decrease concentration
towards substance
of a substance
towards fewer moles of
increase pressure of
system
gas
volume decrease
decrease pressure of
system
for gas: pressure decrease
= volume increase
towards more moles of
gas
increase temperature of
system
away from heat/ energy
extra heat/ energy must
be used up
exothermic reaction is
favored
decrease temperature of towards heat/ energy
system
more heat/ energy needs to be
produced to make up for the
loss
exothermic reaction is favored
add a catalyst
NO SHIFT
The rates of both the forward and reverse
reactions are increased by the same
amount.

Consider the reaction 2 NO (g) + H2 (g) = N20 (g) + H2O (g) with AH° = + 36 kJ. In
which direction, left or right, will the equilibrium shift if the following changes are
made?
a. No is added
b. the system is cooled
c. H2 is removed
d. pressure is increased
e. N20 is added
