注明化学反应条件是书写化学反应方程式的基本要求之一,学生在书写化学方程式时,经常因平时学习忽视搞懂为什么要有这样或那样的反应条件等原因而漏写或错写了反应条件。本文探讨怎样推测化学反应条件的一些规律。 化学反应条件是决定化学反应速度快慢和能否发生反应的重要因素之一。任何一个化学反应都是原化学键被拆开后重新形成新化学键的过程。而化学键的拆开需要能量,化学键的形成又放出能量。所以,当放出的能量能维持反应继续进行时,反应就不需要持续加 It is noted that the chemical reaction conditions are one of the basic requirements of the writing chemical reaction equation. When students write chemical equations, they often miss or write the reaction conditions because they usually learn to ignore why they have such reaction conditions. . This article discusses how to speculate on some laws of chemical reaction conditions. Chemical reaction conditions are one of the important factors that determine the speed of chemical reactions and whether they can react. Any chemical reaction is a process in which new chemical bonds are newly formed after the original chemical bonds are disassembled. The dismantling of chemical bonds requires energy, and the formation of chemical bonds releases energy. Therefore, when the released energy can maintain the reaction, the reaction does not need to continue to increase.
