Kinetic studies

Definition

Kinetic studies involve the investigation of the rates at which chemical reactions occur and the factors influencing these rates. This field helps in understanding how different conditions, such as concentration and temperature, can affect reaction speed, leading to insights in both organic and inorganic chemistry as well as quantitative analysis. By measuring reaction rates, scientists can elucidate mechanisms, optimize reaction conditions, and even design better catalysts.
