Systemic Approach for Numerical Modeling and Simulation of the Impulse Response for Rapid Reaction Cu2+ 驴 S2O32驴

摘要

The kinetics of reaction between Cu2+ and S₂O₃ 2- and formation of an intermediate complex, CuS₂O₃, are investigated. The kinetics of fading away of the color of this complex has been traced spectrophotometrically using a stopped-flow apparatus. The experimental reaction order is consistent with the mechanism involving in the first step complex''s fast formation and in the second, the reaction between two complex molecules. For family of curves y = y(t, p), experimentally rise up, y is the light intensity and it is considered as dependent on time t [ms] and concentration p[mol/l]. We are following the significant stages of identification - numerical modeling and simulation, in a usual systemic variant. The results run on the computer are being compared and interpreted in report to the experimental measurements
