| Abstract: | The thermal dynamic study on the liquid-liquid reaction that potassium permanganate determined the trace nitrite in the water was carried out by microcalorimeter.The thermodynamical parameters(the apparent activation enthalpy thermodynamic parameters,apparent activation entropy and apparent activation free energy),rate constant and dynamic parameters(performance activation energy,frequency factor and reaction series) were obtained by experiment and calculation,and the reaction conditions were investigated by combination of experimental data. |
