Difference Between Thermal Decomposition And Thermal Dissociation
The thermal decomposition and thermal dissociation are two different processes. Thermal decomposition is the process in which a molecule breaks down at high temperatures into smaller molecules. In contrast, thermal dissociation occurs when a single atom or molecule remove from a compound as a result of heat. Let us discuss both processes in detail below:
Thermal decomposition is the process of breaking down a compound by heat. The bonds in a compound are broken and new bonds form in their place. This reaction is exothermic; it gives off energy as it occurs, which means that thermal decomposition reactions can be used to generate heat or light from chemical energy.
Thermal dissociation is the breaking down of a compound into its elements. For example, sodium chloride (table salt) can be broken down into sodium and chlorine. This type of reaction is sometimes referred to as decomposition because it occurs at high temperatures–more specifically, above 1,000 degrees Celsius (1,800 degrees Fahrenheit).
In short, thermal decomposition is the process of breaking down a substance by heating it. Thermal dissociation occurs when a substance breaks down into two or more simpler substances by the action of heat.
In other words, thermal decomposition occurs when you heat up a compound and it breaks down into its constituent elements (for example, burning wood). Thermal dissociation occurs when you heat up water molecules enough that they break apart into hydrogen and oxygen gases (boiling).
The difference between thermal decomposition and thermal dissociation is that the first one involves chemical reactions that occur at high temperatures, while the second one occurs at low temperatures.
