Water calorimetry: a correction to the heat defect calculations.

Journal of Research of the National Institute of Standards and Technology | March 1, 2002| | Copyright

In a recent publication, we used a reaction. model (model III) to calculate the heat defect for the irradiation of aqueous solutions with ionizing radiation at 21 [degrees]C. Subsequent work has revealed that the literature value used for one of the rate constants in the model was incorrect. A revised model (model IIIR) incorporates the correct rate constant for 21 [degrees]C. Versions of models III and IIIR were created for irradiations at 4 [degrees]C. For our current water calorimetry protocol, the values of the heat defect for [H.sub.2]/[O.sub.2]-water (water saturated ...
