Reactant conversion can be measured by analyzing the concentration of reactants and products over time. This can be done using various analytical techniques such as gas chromatography (GC), high-performance liquid chromatography (HPLC), and mass spectrometry (MS). The formula for conversion (X) is given by:
X = (C0 - C)/C0
Where C0 is the initial concentration of the reactant, and C is the concentration at a given time.
