,DEFINITIONS
A closed system An open system
01 A system in which mass is 02 A system in which both energy
and matter can be exchanged
conserved inside the system
but energy can enter/leave the between the system and its
system freely surroundings
Dynamic
A reversible chemical
reaction equilibrium
03 A reaction in which products
04 A reversible reaction in which the
can be converted back into forward and the reverse reactions
reactants are taking place at the same rate.
Concentrations of reactants and
products are constant
, Factors that can change
the equilibrium position of a
system/reaction
Temperature Pressure Concentration
REX: Reduced temp -> Increase pressure -> volume Increase reactant -> forward
exothermic reaction decreases & the system reaction favoured
HEN: Hotter temp -> favours the reaction with Remove product -> forward
endothermic reaction the lowest no. moles reaction favoured
If the no. of
moles are
equal (L=R)
then there's
no effect to
a change in
pressure
