Analysis of Errors in Chemical Reaction Enthalpy Change Experiments and Improvement of Experimental Equipment
Determination of enthalpy change of chemical reaction is a classical experiment in university engineering chemistry experiment.In this paper,the data of 60 students'experimental reports were extracted and analyzed and combined with the problems found by the teachers in the preparatory experiments,the errors of experimental data were analyzed,and the methods of experimental equipment improvement were proposed.
