The theme chemical equilibrium explains a variety of chemical phenomena and is related to other fundamental concepts of the epistemological field of Chemistry. However, it presents many learning troubles, already widely reported in the literature. We present a teaching proposal that involve the student in the process of learning, in a participatory and collaborative way for to form a citizen endowed with intellectual autonomy and critical thinking. The POGIL - Process Oriented Guided Inquiry Learning, was the active methodology used in the sequence of activities planned for the classroom and laboratory. The study was developed as a qualitative research, having as participants subjects the researcher and students of the second year of high school and technical work safety in the State School Teônia Amaral, located in the municipality of Florânia – RN. Data collection was performed through questionnaires, pedagogical test, documents and participant observation. The results of the research evidenced an active participation of the students in the proposed activities. The students presented greater interaction between the peers and the researcher teacher, a higher level of interest and commitment in the activities, as well as a greater ease in the construction of knowledge. Issues with increasing levels of complexity, taking into account students' previous knowledge and discussions at the end of activities, are promising to enhance the understanding of the qualitative aspects of chemical equilibrium. For the most part, the students were able to attribute dynamic character to the chemical equilibrium, and presented the understanding that reagents and products coexist in the same medium of the reaction. As an educational product of this research, we propose a didactic guidebook for high school teachers, containing the didactic unit developed.
