Question

The radioactive nuclide ⁶³Ni decays by a first-order process via the emission of a beta particle. The ⁶³Ni nuclide has a half-life of 160 years. How long will it take for 69% of ⁶³Ni to decay?

Expert Solution

Step 1

Given data:

Half life = 160 years

Now by using relation between rate constant and half life of 1st order reaction.

Let initial concentration of Ni be 100.

69% of Ni has decayed.
