Problem

Two measurements of the half-life for reactant A were recorded with their associated uncertainties. • Trial 1:

[A]_0 = 0.60\,\text{M}

t_{1/2}=90\pm5\,\text{s}

• Trial 2:

[A]_0 = 0.30\,\text{M}

t_{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
