Reversible Reactions

A reaction that can work in both directions i.e. reactants can form products and those products can then react to form the reactants again
EXAMPLE 1 - THERMAL DECOMPOSITION OF AMMONIUM CHLORIDE
The concentrations of the reactants and products in a reversible reaction remain constant if the system is closed. Thowever, the reactions are contiuining continuously in both directions.
The point of equilibrium=Proportion of components in the equilibrium mixture.
1. Factors that affect it
  1. Temperature
  2. Pressure
    1. only applies to gases
    2. <pressure = shifted equilibrium position to direction producing fewer moles of gas
2. There are two main characteristics of a reaction that has reached dynamic equilibrium:
  1. 1. The forward and reverse reactions occur at the same rate.
  2. 2.. The concentrations of reactants and products remain constant.
  3. A reversible reaction will reach dynamic equilibrium in a sealed container (a closed system)
EXAMPLE 2 - HYDRATION OF COPPER (ll) SULFATE
