- How can the rate law for the reaction between crystal violet and excess sodium hydroxide be determined using spectroscopy? (What is the reaction order, rate constant, and half-life for the chemical reaction between crystal violet and excess sodium hydroxidearrow_forwardThe absorption spectra of solutions containing Br2 are solvent dependent. When elemental bromine is dissolved in nonpolar solvents such as hexane, a single absorption band in the visible spectrum is observed near 500 nm. When Br2 is dissolved in methanol, however, this absorption band shifts and a new band is formed. Account for the appearance of the new band. Is the 500 nm band likely to shift to a longer or shorter wavelength in methanol? Why?arrow_forwardA 10 μL aqueous sample containing 1 attogram of Rb+ was injected into a graphite furnace atomic absorption instrument. Calculate the concentration of Rb+ atoms in ppb. The molecular weight of Rb is 85.47 g/mol. density of water = 1.0 g/mL atto = 1 x 10-18 Amazingly, the low concentration of this sample can be detectedarrow_forward
