What is the decay constant for ¹³¹I if the half-life is 8.04 d?

Question

Quizplus · Accepted Answer

The decay constant ($\lambda$) can be calculated using the formula $\lambda = \frac{\ln(2)}{t_{1/2}}$, where $t_{1/2}$ is the half-life. Given the half-life is 8.04 days, first convert days to seconds (8.04 days * 24 hours/day * 3600 seconds/hour = 694,656 seconds). Then, calculate the decay constant: $\lambda = \frac{0.693}{694,656 s} \approx 9.98 \times 10^{-7} s^{-1}$.
