The isotope,tritium,has a half-life of 12.3 years.Assume we have 10 kg of the substance.What will be the disintegration constant (in s ^- ¹)?

Question

Quizplus · Accepted Answer

The disintegration constant (λ) is calculated using the formula λ = ln(2) / half-life. Converting the half-life from years to seconds (12.3 years = 12.3 * 365.25 * 24 * 3600 seconds), and then calculating λ gives approximately 1.8 × 10⁻⁹ s⁻¹.
