If of a radioactive substance has a half-life of , a separate sample of the identically same substan — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Radioactive decay follows first-order kinetics. The half-life ($T_{1/2} = 0.693 / \lambda$) is entirely independent of the initial amount or concentration of the radioactive substance. Therefore, the half-life remains $14\text{ hours}$.
