The decay rate of an isotope is initially R₀,but after one half-life has gone by,the rate is R₀/2.At the end of the NEXT half-life,what will the decay rate be? A) 0 B) R₀/16 C) R₀/e D) R₀/4 E) R₀/e²

Question

Quizplus · Accepted Answer

After one half-life, the decay rate is halved, so it becomes R₀/2. After the second half-life, the decay rate will be halved again, so it becomes R₀/2 * 1/2 = R₀/4. Therefore, the answer is D.
