Consider the radioisotope ⁴¹Ca (half life = 1.03 × 10⁵ years). What is the first-order rate constant for ⁴¹Ca?
Radioactive Decay is a first order process. In 1911 , maria curie prepared a n international radioactivity standard that conatined 22.00 mg of 226 Ra, which has a half life of 1620 years. How much Ra remained in 1977?
Fallout from nuclear weapons tests in the atmosphere is mainly 90Sr and 137Cs , which have 28.6- and 32.2-y half-lives, respectively. Atmospheric tests were terminated in most countries in 1963, although China only did so in 1980. It has been found that environmental activities of these two isotopes are decreasing faster than their half-lives. Why might this be?
5. A reaction has the expeimental rate law = rate = k[A]2[B]. If the concentraion of A is doubled and the concentration of B is halved, what happens to the reaction rate? 11. Studies of radioactive decay of nuclei show that the decay rate of the radioactive sample is proportional to the amount of the radioactive species present. Once half the radioactivity has disappeared, the radioactive decay rate is only half of its original value. Is radioactive decay a zeroth-order, first order, or second order process? 13. Which of these reactions are unimolecular and elementary, which are bimolecular and elementary, and which are not elementary? a. HCl(g) + H2O(g) -----> H3O+(g) + Cl-(g) b.
