How may reaction rates be measured

WebThere are five general properties that can affect the rate of a reaction: The concentration of the reactants. The more concentrated the faster the rate. Temperature. Usually reactions speed up with increasing temperature. Physical state of reactants. WebMay 11, 2024 · Electrochemistry–mass spectrometry is a versatile and reliable tool to study the interfacial reaction rates of Faradaic processes with high temporal resolutions. However, the measured mass spectrometric signals typically do not directly correspond to the partial current density toward the analyte due to mass transport effects.
