Which Graph Below Describes the Decay of Two Radioactive Nuclides

question 27

Multiple Choice

Which graph below describes the decay of two radioactive nuclides, P and Q, when the half-life of Q is shorter than the half-life of P? In these graphs ln[N(0) /N(t) ] is plotted on the y-axis with time (t) on the x-axis. N(0) = number of radioactive nuclides present at time = 0, and N(t) = number present at time = t.
