Oh rate constant
I am having a difficult time determining what is meant by: initial rate = k [A] o I am not sure if the “o” means the initial amount at time zero, or if it is meant to be a General rate equation Rate k A m B n Rate rate of the reaction k rate constant order of the rxn Initial Concentration of H 2 O 2 (moldm -3 ) Initial Rate (x10 -3 The sources of critically evaluated photochemical data for atmospheric modeling, NASA/JPL Publications and IUPAC Publications, recommend uncertainties within 10%-60% for the majority of OH reaction rate constants with only a few cases where uncertainties lie at the low end of this range. The overall rate constant for the reaction OH + CH3COOH → products in the temperature range of 229−300 K was determined using a chemical ionization mass spectrometer coupled to a high-pressure turbulent flow reactor (∼200 Torr of carrier gas N2).
Therefore, the reaction is zero order with respect to [B], and [B] will not appear in the rate law expression. Since doubling [A] increases the rate of the reaction 4-fold, the reaction is second order with respect to A. So, the rate law is: rate = k[A]^2. You can use any trial to calculate the value of the rate constant, k.
20 Jan 2013 Objective: To determine the reaction order with respect to crystal violet and determine the rate constant and half life for the reaction: [CV+ + OH– CO2 + OH- I. HCOI- k--3 reaction, we have corrected our hydration rate constants using Rate of hydration of CO* al 2~5~ in 0.026 M buffer-O.10 M KC1 . Electronically excited OH(2Σ) is formed both by chemical and thermal excitations in the H2-O2 reaction. The OH(2Σ) emission in the partial equilibrium region of I am having a difficult time determining what is meant by: initial rate = k [A] o I am not sure if the “o” means the initial amount at time zero, or if it is meant to be a General rate equation Rate k A m B n Rate rate of the reaction k rate constant order of the rxn Initial Concentration of H 2 O 2 (moldm -3 ) Initial Rate (x10 -3 The sources of critically evaluated photochemical data for atmospheric modeling, NASA/JPL Publications and IUPAC Publications, recommend uncertainties within 10%-60% for the majority of OH reaction rate constants with only a few cases where uncertainties lie at the low end of this range.

The effective rate constant is keff = (k[OH-]y). In other words, the first order rate law works fine, but we get an effective first order rate constant, keff, that includes the effect of the concentration of hydroxide. Keeping [OH-]y constant can be done experimentally by having hydroxide in great
