9. Radioactive Iodine I-131 (also called Radioiodine I-131) therapy is a treatment for an overactive thyroid. The half-life (t1/2) = 8.02 days for the 1st order decay. Calculate the rate constant (k) to 3 significant digits
Added by Jose Carlos J.
Step 1
The formula is: \[ k = \frac{0.693}{t_{1/2}} \] where 0.693 is the natural logarithm of 2. ** Show more…

Iodine-131 is a radioactive isotope that is used to diagnose and treat some forms of thyroid cancer. Iodine-131 decays to xenon-131 according to the equation: I-131 ⟶ Xe-131 + electron. The decay is first-order with a rate constant of 0.138 d^(-1). How many days will it take for 90% of the iodine-131 in a 0.500 M solution of this substance to decay to Xe-131?

A radioisotope of iodine, 131I is used to study thyroid function. A patient is given a sample that is 2.00 x 10-4 M 131I. If the half-life is 8.04 days (a) what is the rate constant, k? (b) what fraction of the radioactivity remains after 14 days? **Radioactive decay is a first order process.

Iodine-131 is a radioactive isotope that is used to diagnose and treat some forms of thyroid cancer. Iodine-131 decays to xenon-131, according to the equation below: iodine-131 → xenon-131 + electron The decay is first order with a rate constant of 0.138 d^(-1). All radioactive decay is first order. How many days will it take for 64.0% of the iodine-131 in a 0.300 M solution of this substance to decay to xenon-131?
