Reaction Kinetics and Dimensional Analysis (a) Consider an example first-order reaction of the nuclear decay of element A: A+B+C where B and C are the products of the decay. The reaction is said to be first-order because, at a given time, the rate at which the molar concentration of A, denoted as [A] (mol/L), decreases is proportional to the molar concentration of A at that time: d[A] dt = -k[A] Here, k, the proportionality constant, is known as the rate constant. Let time be measured in seconds. Determine the units for the rate constant k. The dissociation of hydrogen iodide (a.k.a., HI) is a second-order process, which means d[HI] dt = -k[HI]² et time be measured in seconds. Determine the units for the rate constant k for this particu action.

Geologists can estimate the age of rocks by their uranium-238 content. The uranium is incorporated in the rock as it hardens and then decays with first-order kinetics and a half-life of 4.5 billion years. A rock contains 83.2% of the amount of uranium- 238 that it contained when it was formed. (The amount that the rock contained when it was formed can be deduced from the presence of the decay products of U-238.) How old is the rock?
