Abstract. . Knowing the factors that affect the rate of chemical reactions is essential not only for the entire chemical industry, but also for the daily life of man. Understanding chemical kinetics has proven to be a challenge for students, and many misconceptions have been described in the scientific literature. The purpose of the present research is to to identify the difficulties that Bulgarian students encounter when studying chemical kinetics. The research was conducted using quantitative methods – testing and surveying. A diagnostic test was conducted with 17 eleventh-graders studying “Chemistry and environmental protection” at an advanced level. In addition, a survey was conducted with 39 teachers regarding the difficulties they observed students encounter in learning chemical kinetics. From the obtained results, it can be seen that the Bulgarian students encounter difficulties similar to those found in foreign studies when learning the content of chemical kinetics. It is much easier for students to reproduce presented facts than to work with data in graphical form and draw conclusions based on graphically presented data.
