Abstract

This study aims to analyze the misconceptions on the factors that affect the reaction rate through a qualitative descriptive method. The misconceptions experienced by students are examined through various sources of journals, books, and field experiences. Furthermore, research data was carried out to obtain misconceptions that were often experienced by students and the sources of misconceptions. There are 30 misconceptions on the factors that affect the reaction rate based on the literature. Based on the results of the study, there were three misconceptions experienced by 20 students from the total number of 21 students. The misconception that most students experience are the concentration of reactants increases reaction will take longer because there will be much more particles to collide. In addition, the rate of the same reactions are compared at different temperatures then the reaction with the highest temperature is defined as the rate of reaction. The next misconception is the temperature increase in an exothermic reaction can increase the forward rate and decrease the reverse rate because the equilibrium shifts to the right. Misconceptions are caused by information sources from the internet, teacher teaching in schools, textbooks used by students, and everyday life experiences of students.
