众所周知,影响化学反应速度的主要因素是温度、浓度和催化剂,而温度尤为显著。目前公认的看法是:当反应物浓度保持不变时,温度每升高10℃,化学反应速度大约增加2～4倍。温度升高不仅加快反应速度,使较低温度下难以进行的反应得以进行,而且随着加热温度的变化,反应产物也常随之改变,因为温度的变化引起了反应过程中物质结构的变化。因此,研究控制反应温度问题,无论在生产、实验中,还是在理论研究中,都有重要的
As we all know, the main factors affecting the speed of chemical reactions are temperature, concentration and catalyst, and the temperature is particularly significant. The currently accepted view is that when the reactant concentration is kept constant, the chemical reaction rate increases by approximately 2 to 4 times for every 10°C increase in temperature. The increase of temperature not only accelerates the reaction rate, but also makes it difficult to carry out the reaction at a lower temperature. With the change of the heating temperature, the reaction product often changes with it, because the temperature change causes a change in the structure of the material during the reaction. Therefore, it is important to study and control the reaction temperature, whether it is in production, experiment or theoretical research.
