The air pollutant NO is produced in automobile engines because of the high-temperature reaction below. If the initial concentrations of N2 and O2 at 1000 K are both 1 M, what are the concentrations of NO, N2, and O2 when the reaction mixture reach..
A reaction is begun with a reaction mixture containing the following: [dye] = 1.0 x 10-4 M [bleach] = 0.10 M When [dye] = 8.0 x 10-5 M the rate is determined to be 3.74 x 10-7 M/min. When [dye] = 4.0 x 10-5 M the rate is determined to be 1.71 10-7..
Most organic polymers are named based on the monomers used in their production. However, poly(vinyl alcohol) (PVA) is not made from vinyl alcohol,
Are there hints in the data provided which would aide in choosing which integrated rate law to use? Also, if they were to give you the rate law for the overall equation, would you use the overall order's integrated rate law or the specific reactan..
