EQUILIBRIA
Some reactions are reversible, shown by the sign ""
If a reversible reaction takes place in a closed system, equilibrium can be
reached.
This is when there is a balance between the products and the reactants and
concentrations of them stay the same.
The reactions have not stopped, the rate of the forward reaction is just
equal to the rate of the reverse direction this is called dynamic equilibrium.…read more

chatelier's principle states that the position of equilibrium will shift to
decrease the pressure i.e. in this case, the equilibrium moves towards
the right side of the reaction.
Note: The position of equilibrium will not be affected is when there
are the same number of moles of gases of each side of the equation.
The position of equilibrium will not be affected by change in
pressure.
3. Changing the temperature: This is dependent on the value of enthalpy
change.…read more
