Description
7.1 - Dynamic Equilibrium
- Equilibrium- the rate of the
forward reaction is equal to
the rate of the backward
reaction
- I.e. when the gradients
of both reactions in a
concentration-time
graph is zero and equal
- I.e. when the gradients
of both reactions in a
concentration-time
graph is zero and equal
- Dynamic
- The reaction has not stopped-
both the forward reaction and
backward reaction are still
occuring
- The reaction has not stopped-
both the forward reaction and
backward reaction are still
occuring
- Acheived in a closed system
- Since a closed system rpevent the
exchange of matter from the
surroundings, the reactants and
products can react with each other
only
- Since a closed system rpevent the
exchange of matter from the
surroundings, the reactants and
products can react with each other
only
- Concentrations remain constant
- Both reactants and products
are produced and destroyed at
an equal rate, so their
concentrations do not change
- Both reactants and products
are produced and destroyed at
an equal rate, so their
concentrations do not change
- No change in macroscopic properties
- Observable properties such as
colour and density do not
change becahse they depend
on the concentrations, which
remain constant
- Observable properties such as
colour and density do not
change becahse they depend
on the concentrations, which
remain constant
- Can be reached from either direction
- That's why there are arrows
from boths directions.
