Usando um calorímetro isoperibólico no laboratório didático de uma forma diferente

TL;DRAbstract

This work consists of utilizing an isoperibol calorimeter in educational laboratories of the chemistry college undergraduate course to study unusual aspects of some processes, in addiction to the energetic. As you know, the calorimeter is the main instrument of the first thermodynamic law and, normally, is used to obtain the variation of energy in physical and chemical phenomenon, such as enthalpies of dissolution, combustion, neutralization and other reactions. In this project, the calorimeter was used to study the kinetics of chemical reactions, determining the enthalpies of vaporization, the enthalpies of electrochemical reactions and oscillatory reactions. The instrument used is an isoperibol calorimeter and it has already been in use in the Physical Chemistry Laboratory of the Unicamp Chemistry Institute for a long time. The study of the kinetic of reactions between MnO 4 and C 2 O 4 2 inside an acid environment showed that the reaction is autocatalyzed by Mn 2+ . Through this tec
