化学反应的发生受反应物的种类和性质、化学环境等因素的影响.存在反应的顺序,主要包括反应的历程和竞争反应等.化学环境主要指:反应物浓度、反应的条件(温度、压强、催化剂、酸碱性、恒温恒压、恒温恒容)等.1化学反应的历程2种物质之间的反应,也存在逐步反应,存在中间产物.有些是离子间的逐步结合,有些是在水溶液中
The occurrence of chemical reaction is affected by the type and nature of the reactants, the chemical environment, etc. The order of the reaction includes the reaction course and competition reaction, etc. The chemical environment mainly refers to the concentration of the reactants, the reaction conditions (temperature, pressure , Catalysts, pH, constant temperature and constant pressure, constant temperature and constant), etc. 1 The course of chemical reaction The reaction between two substances, there are also gradual reaction, there are intermediate products. Some are the gradual combination of ions, some in In water
