Rate Constant for Second Order Reaction is usually measured using the Liter per Mole Second[L/(mol*s)] for Second Order Reaction Rate Constant. Cubic Meter per Mole Second[L/(mol*s)], Cubic Meter per Kilomole Millisecond[L/(mol*s)], Liter per Mole Millisecond[L/(mol*s)] are the few other units in which Rate Constant for Second Order Reaction can be measured.
