11 Properties of Radioactivity Prelaboratory Questions Name Laboratory Section 1. The decay behavior of a radioactive substance obeys first order kinetics: In (N/N.) = -kt, where N is the amount of radioactive nuclei at time = t seconds, N, is the amount at t = 0 seconds, k is the first order rate constant, and t is the elapsed time. If the half-life of the radioactive nuclei is 10 minutes, calculate the amount that remains after 75 seconds. (Hint: at...
