1) Reaction enthalpy: The standard enthalpy of reaction is the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, when all reactants and products are in their standard states. Unit: typically J/mol
2) dTad: Termperature change under adiabatic conditions. Expressed in K. Calculated as Q/cp
3) TMRad: Time to maximum reactionrate under adiabatic conditions. Oftentimes it is the time until runaway occurs
4) Onset temperature Texo: This is the temperature on the dynamic DSC at which the very first evolution of the heat can be detected.
5) Kühlleistung = heat removal qex
6) Thermische leistung = reaction heat -> shows how much heat energy evolves during the reaction per time unit
7) Specific reaction heat: heat evolved int he course of the reaction. q is usually expressed in J/g
8) Specific heat capacity: Informally, it is the amount of energy that must be added, in the form of heat, to one unit of mass of the substance in order to cause an increase of one unit in its temperature. Units = [J/(K kg)]
