Problem

A reactant A was studied under two different initial concentrations. Experiment 1: [A]0=0.20 M[A]_0 = 0.20\,\text{M}, t1/2=80 st_{1/2}=80\,\text{s} Experiment 2: [A]0=0.10 M[A]_0 = 0.10\,\text{M}, t1/2=40 st_{1/2}=40\,\text{s} Which reaction order with respect to A is most strongly supported by the data? (a) Second order (b) Zero order (c) First order (d) Cannot be determined from the given data
