A reversible chemical cell of molten potassium nitrate
A reversible galvanic cell of molten potassium nitrate is described. It is represented by the following scheme: K(1)/KNO<sub>3</sub>(l)/NO<sub>2</sub>(g),O<sub>2</sub>(g)/Pt(s). The theoretical standard emf calculated from thermochemical data for the reaction K(I)...

| Sumario: | A reversible galvanic cell of molten potassium nitrate is described. It is represented by the following scheme: K(1)/KNO<sub>3</sub>(l)/NO<sub>2</sub>(g),O<sub>2</sub>(g)/Pt(s). The theoretical standard emf calculated from thermochemical data for the reaction K(I) + NO<sub>2</sub>(g) + ½O<sub>2</sub>(g) = KNO<sub>3</sub>(l) is in very good agreement with the one deduced from the experimental results. The standard emf of the cell is given by E ° = 5∙440 + 3∙812 × 10<sup>-4</sup>T 1n T - 6∙231 × 10<sup>-8</sup>T<sup>2</sup> + 2∙623/T - 5∙156 × 10<sup>-3</sup>T. |
