Determination of the heat of formation of water

 Product No: P3021501

Principle

Standard molar enthalpies of formation ΔBHΦ are important compiled thermodynamics tabulation quantities for calculating standard enthalpies of reaction for any arbitrary reaction. They are defined as the heat of reaction occurring in the direct formation of one mole of the pertinent pure substance from the stable pure elements at constant pressure. For spontaneous and quantitative formation reactions, e.g. the conversion of hydrogen and oxygen to water, standard enthalpies of formation can be measured directly using calorimetry.

Tasks

  1. Determine the enthalpy of formation of water by burning 100 ml H2 in a closed glass jacket calorimeter.
