用分光光度法初步研究了HClO4体系中尿素与HNO2的反应动力学,得到了反应速率常数,确定了动力学方程。往含有不同尿素浓度的HClO4中加入NaNO2溶液,在反应初始阶段,以溶液中HNO2的吸光
The reaction kinetics of urea and HNO2 in HClO4 was studied spectrophotometrically. The reaction rate constant was obtained and the kinetic equation was determined. NaNO2 solution was added to HClO4 containing different urea concentrations. At the initial stage of reaction, the absorbance of HNO2 solution
