This article examines the relationship between physics concepts in teaching chemistry concepts, especially the importance of understanding physical principles in teaching chemical kinetics. The aim of this study is to identify and explain the effect of various factors such as temperature, catalysts, and concentration on the rate of reactions, so that this understanding can help improve educational processes in this area. An experimental and analytical approach was used in this research. Experiments were conducted to investigate the effect of temperature, pressure, concentration of reactants, and type of catalysts. Temperature changes in the range of 20 to 80 ° C, pressure from 1 to 5 atmospheres, and changes in the concentration of reactants were systematically investigated from 0.1 to 2 molar, and data collection was carried out by measuring reaction time and changes in the concentration of substances. The results showed that as the temperature increased, the kinetic energy of molecules increased, resulting in faster reactions. The results also show that the use of catalysts reduces the activation energy and increases the rate of reactions. The results clearly showed that the concentration of reactants, as an important factor, has a significant effect on the rate of reactions, and these findings confirm the links between physical and chemical concepts. Overall, this article emphasizes an interdisciplinary approach that can help to gain a deeper understanding of scientific concepts and is important in designing and predicting the behavior of chemical reactions in real applications. Improving science education by integrating physics and chemistry concepts can prepare a new generation of students for success in scientific and industrial fields.
