Problem

A certain radioactive nuclide undergoes first-order decay with a measured half-life of

1.20\times10^{4}\,\text{s}

. What is the value of the rate constant

k

for this decay? a)

8.3\times10^{-5}\,\text{s}^{-1}

5.8\times10^{-5}\,\text{s}^{-1}

1.7\times10^{-4}\,\text{s}^{-1}

5.8\times10^{-4}\,\text{s}^{-1}
