Double decomposition reactions are double replacement reactions in which 2 SPECIES COMBINE TO GIVE A SINGLE PRODUCT BUT, Species SWITCH THEIR PARTNERS!

NaOH + HCl → NaCl + H2O
Thermal decomposition reaction are those in which A SINGLE REACTANT breaks into Two or Both!!! APPLYING HEAT

The extent of a reaction means the time of reaction between the elements/substances to reach the chemical equilibrium. And the degree of dissociation is the extent of dissociation/breaking of a substance into it's ions, in a given liquid medium, like water. It varies with respect to time, that is, it increases with time till the solution becomes saturated and can no more dissolve the substance.

Dissociation reaction is called endothermic reaction as it requires the input of heat energy in order to be broken down into its components. Dissociation reaction is one in which a compound dissociates( gets broken down) into its components.

Thermal dissociation:- it is a reversible reaction in which a substance breaks or split into two or more simple substance or molecules by the application of heat. While
Thermal decomposition:- It is a natural process a substance decay into many simple or complex or enacted form due to natural environment conditions.

(1) In a double displacement or double decomposition reaction two compounds react to form two other different compounds by way of interchange of ions.
Thus, lead nitrate and potassium iodide interchange ions in aqueous medium to form insoluble lead iodide and soluble potassium nitrate.
2Pb(NO)3 + 2KI —> PbI2 + 2KNO3
But in a thermal dissociation, one compound breaks up into two or more different substances under the influence of heat.
For example, lead nitrate on heating decomposes to give lead monoxide, nitrogen dioxide and elemental oxygen.
2Pb(NO3)2 ---> 2PbO + 4NO2 + O2
(2) In a double decomposition, the two products are always compounds.
In thermal decomposition, the products could be either two elements or two compounds or a combination of both elements and compounds, depending on the nature of the compound that undergoes decomposition.
2HI → H2 + I2
(Both the products are elements)
CaCO3 →CaO + CO2
(Both the products are compounds)
2Pb(NO3)2 --> 2PbO + 4NO2 + O2
(The first two products are compounds and the third one is an element)
(3) A double decomposition reaction is always a non-redox reaction. The reaction does not affect the oxidation number of any element as it only involves interchange of ions.
A thermal decomposition may or may not be a redox reaction. When one or more element are formed as products, the decomposition is a redox reaction. The decompositions of HI and Pb(NO3)2 illustrated above are redox reactions. But the decomposition of CaCO3 is non-redeox as there is no change in the oxidation number of any element in the formation of CaO and CO2 as products.

Dissociation corresponds to separation of ions from each other in a given polar solvent like water. The total number of cations & anions remains always equal (charge neutrality principle) .These ions are solvated(sarrounded by solvent molecules with oppositely charged polar part of solvent)
NaCl(ionic solid) —-> Na(+) aq + Cl-(aq) .
HCl [covalent](g) + aq —-> H+ (aq). + Cl(-)I
Decomposition is normally breaking of ( usually) a solid into two or more substances (on heating, thermal) . Products are normally compounds in any physical state.
