2. Chemistry. The direct separation of compound substances into their primary elements, or into less complex compounds; decomposition, spec. by the action of heat. Hence dissociation-point, the temperature at which such decomposition takes place; dissociation constant, the product of the concentrations of the dissociated ions in a solution divided by the concentration of the undissociated molecule when equilibrium has been reached. Applied usually to the separation of a compound into its elements by the action of heat alone, without the intervention of any substance which breaks up the combination by its greater chemical affinity for one of the elements; but sometimes restricted to such a partial separation of the elements, that they reunite when the temperature is lowered below the dissociation-point. Others have used it in the wider etymological sense of direct separation of elements by any force, and applied thermolysis n. to dissociation by heat, as distinguished from electrolysis n. or decomposition by electricity.
