Question

Radioactive decay is a process that follows first-order kinetics. The half-life of $^{64}Cu$ is 0.03507 years; how long (in days) would it take for the amount of $^{64}Cu$ to decrease to 50.04% of its initial amount? Key Concept: Half-life for first order reaction. $t_{1/2} = 0.693/k$. Strategy: Determine rate constant and then calculate time using integrated first order rate law.

Step 1

The half-life of 64Cu is given as 0.03507 years. We can use the formula for the half-life of a first-order reaction to determine the rate constant (k). t1/2 = 0.693 / k Rearranging the equation, we can solve for k: k = 0.693 / t1/2 Substituting the given Show more…
