Abstract:: A Stopped-flow Spectrometer serves as a source for monitoring reactions that occur in timeframes as fast as milliseconds. The instrument mixes the reactants and examines the reaction’s kinetics using a suitable spectroscopic probe. The experiment explores the Stopped-flow kinetics of the formation of Iron (III) Thiocyanate Complex – a four-step reversible system, governed by various rate and acid dissociation constants1. The experiment was performed under Pseudo-first order conditions and the rate constants for the overall reaction, as collected by the spectrometer at 440 nm, 450 nm, and 460 nm for different Fe3+ and H+ concentrations, were used to ultimately find the rate constants derived in the integrated rate law equation. The results were then compared with the reported values.
