| Abstract: | In recent years doubts have often been expressed about the precision and accuracy of isoperibolic calorimeters of the type illustrated in Fig. 1. We assess the validity of such statements by means of experiments on “blank systems,” here Pt cathodes polarised in 0.1M LiOD/D2O. The differential and integral heat transfer coefficients are evaluated, and it is shown that the latter based on backward integration of the data sets should be used in accurate evaluations of the experimental data. It is shown that the precision is better than 99.99% while the accuracy is close to this figure. The high precision and accuracy allow the determination of enthalpy generation due to the reduction of oxygen electrogenerated in the cell. It is shown that this was 0.0011W for the experiments in question, whereas the input enthalpy to the cell was 0.8W for these particular experiments. |
