For the following questions, we are to determine the units for the constant k . A third order reaction overall, where the rate is measured in mol L-1 s-1 and the concentrations of all reactants are measured in units of mol L-1. A rate law that has the concentration of two reactants measured in M, each first order and a rate that is measured in mol L-1 min-1 A reaction where there are multiple products but only a single reactant that is found to be zero order. The rate is measured in units of g s-1
