The kinetics of the reversible thermal decomposition of solids, simplified as A(s) ⇌ B(s) + C(g), is universally described, as a function of temperature (), degree of reaction (), and partial pressure of gaseous product ((C(g))) concerning the equilibrium pressure (()) of the reaction, with the aid of an accommodation function (((C(g)), ())). The kinetic curves of the reaction at different (C(g)) values form a specific surface in the extended three-dimensional kinetic coordinate (, , ln[(dα/dt)/((C(g)), ())]). The coordinate surface is characterized in terms of isoconversional and isothermal kinetic relationships. The apparent Arrhenius parameters that characterize the coordinate surface are related to the intrinsic Arrhenius parameters by considering the thermodynamic parameters of the reaction. In addition, all sets of Arrhenius parameters determined using the extended kinetic approach are correlated with the kinetic compensation effect. Herein, the extended kinetic approach was demonstrated, as exemplified by the thermal decomposition of CaCO.

固体可逆热分解的扩展动力学方法：考虑气态产物效应和动力学补偿效应的通用描述

固体可逆热分解动力学，简化为 A(s) ⇌ B(s) + C(g)，被普遍描述为温度 ()、反应程度 () 和气态分压的函数借助于调节函数 (((C(g)), ())) 涉及反应平衡压力 (()) 的乘积 ((C(g)))。不同(C(g))值下的反应动力学曲线在扩展三维动力学坐标中形成特定曲面 (, , ln[(dα/dt)/((C(g)), ())] ）。坐标表面以等转化和等温动力学关系为特征。通过考虑反应的热力学参数，表征坐标表面的表观阿伦尼乌斯参数与固有阿伦尼乌斯参数相关。此外，使用扩展动力学方法确定的所有阿伦尼乌斯参数集都与动力学补偿效应相关。在此，以 CaCO 的热分解为例，证明了扩展动力学方法。
