Dcp ce hess s law essay hess’s law mengyuan wu (millie) 7 january, 14 aim: the purpose of this experiment is to determine the enthalpy change for the reaction: introduction: it is impossible to measure the enthalpy change for this reaction directly because the process cannot be controlled.
Heat of reaction and hess’s law introduction: hess’s law is a very useful relationship that allows the calculation of the heat of reaction for reactions on paper (without carrying out an actual experiment of that particular reaction.
Based on the results in our experiment, it is clear that hess’s law is an acceptable method to calculate enthalpies of reactions despite the sources of error, hess’s law still proved to provide a result, which was close to the accepted value. Aim to investigate the effect of molar mass on the molar heat of combustion of adjacent members of a homologous alcohol series introduction chemists refer to the energy stored in a substance as the heat content or enthalpy of the substance.
