- 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. Please write down the rate equations for DMA, NH2C1, DMCA, UDMH and NDMA.arrow_forwardYou wish to add enough NaOCl (sodium hypochlorite) to a 150 m³ swimming pool to provide a dose of 5.0 mg/L TOTOCI as Cl2.

(10 pts) (atomic weight: Na 23, O 16, C1 35.5) (b) The pH in the pool after the NaOCl addition is 8.67. To improve disinfection, you want at least 90% of the TOTOCI to be in the form of HOCI (pKa 7.53). Assuming that HOCI/OCI is the only weak acid/base group in solution, what volume (L) of 10 N HCl must be added to achieve the goal?
