Half-Life
10PRACTICE PROBLEM
Using spectroscopy, a first-order reaction was observed at 380 nm. The reaction was allowed to occur in a 1.00 cm sample cell. The only colored species in the reaction at the specified wavelength had a 4.73x103 M-1 cm-1 extinction coefficient and 3.89x10-4 s-1 decay rate. Based on this, what is the half-life of the reaction?
