Some Points on Non-Isothermal Kinetics

If the reaction has a thermal activation character, changes in temperature lead to changes the rate constant. This relationship is often described by the Arrhenius equation  

the rate constant depends on temperature. In the case of the altering temperature the rate constant also becomes a function of time. Consequently, when solving the direct kinetics problem, we have to add the corresponding equations (the temperature over time relationships) to the reaction model. 

Let s consider one of the non-isothermic kinetics cases. Some amount of germanium (IV) chloride is being heated. The heating is accompanied by a consequent decomposition  

Assume the heat exchange is organized in a way that the heating appears with a constant rate 7 = 10K min. One is asked to establish how the gross mass of solids will change if 0.002 mol of GeC is being heated. The initial temperature is 298 K. It is known that the Arrhenius relatimiships for the rate constants have the following form
