摘要：
The rate of nitrogen isotope exchange between NO and HNO3 has been measured as a function of nitric oxide pressure 0.1-0.4 MPa for 1 and 2 M.l(-1) HNO3. It is concluded that N-15/N-14 change rate in NO-HNO3 system has a linear dependence of NO pressure as indicated by rate measurements at different NO partial pressure and constant overall pressure, by adding helium in reactor. Using the rate law: R = k[HNO3](2)[N2O3] the N-15/N-14 exchange rates for nitric acid concentrations 1.5-10 M.l(-1) were calculated.
