Историческото развитие на идеите за химична обратимост и химично равновесие – основа за преподаването и изучаването им
Historical Development of the Conceptions of Reversibility and Chemical Equilibrium – A Base for Their Teaching and Learning

Summary/Abstract: Chemical equilibrium is a key conception in chemistry education both at high school and university. The teaching and learning of chemical equilibrium are associated with difficulties which can be related to the introduction of specific historical views. In the present research a review of the historical development of key conceptions, related to chemical equilibrium, is conducted, namely – incomplete reactions, reversibility, equilibrium constant and dynamics. The possibilities of applying that part of the history of chemistry in teaching context are discussed for better understanding of the contents and nature of science; for using teaching methods, which develop students’ thinking and improving the understanding of teachers of students’ difficulties and misconceptions.
