The thermochemical reaction of Ca (OH) 2 /CaO is reversible, endothermic or exothermic step based on the following reversible solid-gas reaction: (1) Ca OH 2 s + Δ H → CaO s + H 2 O g (2) CaO s + H 2 O g → Ca OH 2 s + Δ H. Δ H is the enthalpy of reaction, and the magnitude of enthalpy and its influencing factors will be described later.
