Problem

Two measurements of the half-life for reactant A were recorded with their associated uncertainties. • Trial 1: [A]0=0.60 M[A]_0 = 0.60\,\text{M}, t1/2=90±5 st_{1/2}=90\pm5\,\text{s} • Trial 2: [A]0=0.30 M[A]_0 = 0.30\,\text{M}, t1/2=93±5 st_{1/2}=93\pm5\,\text{s} Considering the experimental uncertainty, which reaction order with respect to A cannot be ruled out? (a) Second order (b) First order (c) Zero order (d) Third order
