Abstract

This plan aims to contribute on the mechanisms of conceptualization and the notion of Chemical Equilibrium. It should be noted that this is an issue that has to generate many confusions in students both the basic and graduate education, especially regarding the submicroscopic representation. Thus, students will investigate the Federal University of ABC already studied the chemical transformations. The data is analyzed based on the Theory of Conceptual Fields Gerard Vergnaud. As a result of this research is intended to access the operational invariants needed by students in situations that deal with the state of equilibrium, chemical and deepen the discussion on how to give the combination of these elementary cognitive ones.
