To spectrophotometrically determine the mass percent of cobalt in an ore containing cobalt and
some inert materials, solutions with known [Co?) are prepared and absorbance of each of the
solutions is measured at the wavelength of optimum absorbance. The data are used to create a
calibration plot, shown below.

- N-nitrosodimethylamine (NDMA) is a suspected carcinogen that can form via reactions between dimethylamine (DMA) and monochloramine (NH2Cl). The relevant elementary reactions and the corresponding rate constants are as shown below. Reaction Rate constant (M¹s¹) DMA + NH2Cl = DMCA + NH3 k =1.4×10-1, kr = 5.83×10-3 1.28×10-3 DMA + NH2Cl → UDMH UDMH + NH2Cl → NDMA -> 1.11×10-1 If the initial concentrations of DMA and NH2Cl are given, you should be able to predict the concentrations of all species at any given reaction time.
