Consider the radioisotope ²⁴⁰Pu (half life = 6.56 × 10³ years). What is the first order rate constant for ²⁴⁰Pu?
Added by Wendy C.
Step 1
The formula that relates the half-life (\(t_{1/2}\)) to the rate constant (\(k\)) for a first order reaction is: \[ k = \frac{0.693}{t_{1/2}} \] where \(0.693\) is the natural logarithm of 2. ** Show more…

OBJECTIVE. Calculate the concentration-time behavior for a first-order reaction from the rate law and the rate constant. The half-life of uranium-235, the major radioactive component of naturally occurring uranium, is $7.04 \times 10^{8}$ years. (a) What is the rate constant for the radioactive decay of uranium-235, in $\mathrm{y}^{-1}$ and $\mathrm{s}^{-1}$ ? (b) What percentage of original uranium- 235 is left after $4.5 \times 10^{9}$ years?
