QUESTION 1 Radioactive decay is a process that follows first-order kinetics. The half-life of 241 pu is 13.00 years; how long (in hours) would it take for the amount of 241 Pu to decrease to 49.48% of its initial amount? Key Concept: Half-life for first order reaction. t = 0.693/k. Strategy: Determine rate constant and then calculate time using integrated first order rate law.
