Equillibrium - Coggle Diagram

- - - - When the reactants and the products are in equilibrium it is known as an equilibrium mixture
    - - \[K_c = \frac{[C][D]}{[A][B]}\]
        
        This equation does not produce a constant value for equilibrium constant
        
        \[ K_c = \frac{[C]^c [D]^d}{[A]^a [B]^b} \]
  - - - At a point, concentration of reactants and products become constant
    - - The constancy is still attained - backward reaction
      - Different forms of ammonia and hydrogen molecules are formed (combinations with deuterium)
- - - - Melting/Freezing Point
        
        At atmospheric pressure, the temperature at which the solid and liquid of the substance remains at equilibrium
        
        E.g.: Water and Ice remain at equilibrium at 1 atm and 273 K
      - Characteristics
        
        The processes occur simultaneously
        
        The processes occur at the same rate
    - - Equilibrium Water Pressure
        
        Pressure at which the concentration of water remains constant at the given temperature
        
        Vapour pressure of water increases with temperature
      - Normal Boiling Point
        
        Temperature at which the concentration of liquid and gases of that substance remains constant
        
        E.g.: For water, the normal boiling point is 373 K
    - - Equilibrium is seen when the rate of conversion of solid-vapour is equal to the rate of conversion of vapour-solid
      - Examples of Sublimes: Iodine, Camphor, Ammonium Chloride
- - - - More solute cannot be added to it at the given temperature
      - Dynamic Equilibrium exists
        
        Rate of dissolution of substance = Rate of crystallisation of substance
        
        This continues until a constant value is reached between the two
      - E.g.: Sugar in water
  - - - The mass of gas dissolved in a given mass of solvent at a temperature is proportional to the pressure of gas above it
    - - When bottle is opened, the liquid carbon dioxide gets into equilibrium with the gaseous carbon dioxide above it
