Problem

A reactant A was studied under two different initial concentrations. Experiment 1:

[A]_0 = 0.20\,\text{M}

t_{1/2}=80\,\text{s}

Experiment 2:

[A]_0 = 0.10\,\text{M}

t_{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
