摘要：

The apparent values of n for the reduction of NO, HNO2 and NO2 in acidic halide solutions of intermediate concentration have been determined coulometrically. The value of napp for HNO2 is 1.0 in HCl solutions for intermediate flow rates at potential values in the range of the first two cathodic waves observed in voltammetric data. The value of napp exceeds 1.0 at low flow rate. The values of napp for reductions of NO in 5 M HC1 and NO2 in 3.0 M HClO4 containing 0.1 M bromide are 0.5. These results are explained on the basis of chemical reactions coupled to the electrode processes. © 1979.
