Um modelo epistemológico de referência em cálculo e cinética de reações químicas.

In this article, we resume discussions about the application of Differential and Integral Calculus in the Teaching of Chemical Kinetics in Teacher Training. Aspects aimed at demonstrating statements through the resolution of tasks in a course of studies and research as a strategy aimed at appropriating concepts in the domain of reaction kinetics, in the context of activities based specifically on the Anthropological Theory of the Didactic (ATD), based on epistemological models of reference and the dominant one around the object speed laws of chemical reaction. Along the way, the importance and reason for being of Integral and Differential Calculus techniques for teacher training and the formulation of didactic organizations that can serve as support for tasks in the exercise of the profession in high school were highlighted, highlighting the use of instruments of ICT, such as Excel, in the construction of these tasks. It was observed that throughout the course the students understood the steps proposed in the reference epistemological model by completing a crucial task, associated with the question that generated the course, which necessarily applies integration and differentiation techniques to obtain ordinary differential equations, associated with the technique analysis of the least squares method, for the kinetic characterization of a chemical system, a medicine in the simulation of the experimental determination of its expiration date.
