EQUILIBRIUMTopic position of equilibrium
:
Le Chatelier's
principle if a system at equilibrium -
is subjected to change the position of equilibrium,
will shift in order to minimize the
change

Change in pressure
-if NH3
increases
volume of container is reduced , pressure
4 mol of gas 2md of gas
then position of equilibrium shifts to the right
hand side-forward reaction is faster than reverse
reaction
?

There are less gaseous moles on right hand
