The goal of their development is to provide another option aside for the exercises provided in the textbook. The experiments given are on the topics of enthalpy of processes and factors affecting the reaction rate. The new exercises are easy for the students, the results are consistent and close to theoretical, and achieve the base goals of the original experiments.
