Ch ical chemistr Reaction Kinetic Measurement of reaction rates Physical method More accurate and less tedious Measures a physical property of the reaction system as a function of time This allows the reaction to be followed continuously as it proceeds 物理方法 用各种物理性质测定方法(旋光、折射率、 电导率、电动势、粘度等)或现代谱仪(R、 UV-ⅥS、ESR、NMR、ESCA等)监测与浓度 有定量关系的物理量的变化,从而求得浓度变 化。物理方法有可能做原位反应。 1212 Physical Chemistry Measurement of Reaction Rates Physical Method Measures a physical property of the reaction system as a function of time. This allows the reaction to be followed continuously as it proceeds. More accurate and less tedious 物理方法 用各种物理性质测定方法（旋光、折射率、 电导率、电动势、粘度等）或现代谱仪（IR、 UV-VIS、ESR、NMR、ESCA等）监测与浓度 有定量关系的物理量的变化，从而求得浓度变 化。物理方法有可能做原位反应。 Reaction Kinetics
