Thermochemistry. The clinker manufacturing process requires a large input of energy. Part of this is due to heat losses from a process that is less than efficient, but even in an efficient process, the chemical reactions involve an input of energy - an endothermic enthalpy change that can be derived from thermochemical first principles.

12.3: Heat Capacity, Enthalpy, and Calorimetry. Hess's law is that the overall enthalpy change for a series of reactions is the sum of the enthalpy changes for the individual reactions. For a chemical reaction, the enthalpy of reaction (ΔH) is the difference in enthalpy between products and reactants; the units of ΔHrxn are kilojoules per mole.
