| Abstract: | A simple experimental devices were established for the study of the kinetics of reaction between NaNO2 and NH4Cl in the practice of extracurricular scientific and technology active of college students.The results showed that the reaction was a second order reaction and the reaction rate constant(k) was in direction proportion to the H+ concentration in the system.The activation energy of this reaction was 50.26 kJ/mol.The kinetic formulation of this reaction was dC/dt=-2.066×107CH+e-6045/TC2.Based on this experiment,the comprehesunsion for chemical kinetic and its application of students would developed. |
