established in a ______ ______ and
can be set up from
__________________. At equilibrium,
a _________ between the _____ and
_______________. _____ ______ are
______ as _________ and
_________________.


1.6.1
physical
ZQ

,• An equilibrium can only be
established in a closed system
and can be set up from either
direction
• At equilibrium, a natural
balance between the products
and reactants is reached
• Chemical equilibria are
dynamic as both the forward
and reverse reactions continue
to occur

,Name two key
features of
dynamic
equilibrium.

ZQ

, • The rate of the forward
reaction (→) equals the
rate of the
reverse/backwards
reaction (←)
• The concentration of
reactants and products
remains constant at
equilibrium
