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.
