Rate Constant for Zero Order Rxn for Multiple Rxns is usually measured using the Mole per Cubic Meter Second[mol/m³*s] for Reaction Rate. Mole per Liter Second[mol/m³*s], Millimole per Liter Second[mol/m³*s] are the few other units in which Rate Constant for Zero Order Rxn for Multiple Rxns can be measured.
