Which of the following statements correctly describe the kinetics of radioactive disintegration? — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Options A, B, and C are correct. Radioactive decay follows first-order kinetics ($A = \lambda N$), where the rate is proportional to the undecayed amount. The average life is given by $T = 1/\lambda = 1.44 T_{1/2}$. Option D is incorrect because radioactive decay is a nuclear phenomenon completely independent of external physical and chemical conditions like temperature, pressure, or chemical state.
