Ethanol oxidation rate equation

Write the form of the rate equation for the oxidation of ethanol (C2H5OH). The reaction has been experimentally determined to be first order in ethanol and third order in oxygen (O2). 

One of the first studies of rare earth oxide catalysis has been performed by Cremer (1929) on the dehydration of ethanol. In this pioneering work it was shown that the activation energy increased in the series Sc-Y-La, while almost constant activation energy was found along the lanthanide series from Ce to Dy. As the activity of the catalysts increased with increasing activation energy, a correlation between the preexponential factor and the activation energy in the rate equation, the compensation effect, has been formulated (Cremer, 1929). 

As a result, nitroalkene (42a) is almost completely isomerized into N-oxide (47a), which is stable up to 100°C (167). Isomerization proceeds smoothly both in solutions and the solid state. The isomerization rate is approximated by the first-order equation and depends on the polarity of the solvent (isomerization in hexane occurs 70 times more slowly than that in ethanol). 

Direct metallation of methylenecyclopropane with butyllithium in THF affords meth-ylenecyclopropyllithium. This reacts with carbonyl electrophiles such as aldehydes, ketones and lactones by ring alkylation to give selectively 2-methylenecyclopropyl carbinols. No products of exo alkylation are isolated. Other bases such as r-BuOK and KH do not deprotonate methylenecyclopropane. Use of diethyl ether as the solvent, instead of THF, significantly reduced the rate of lithiation. Similar reaction of the lithium reagent with ethylene oxide gave 2-(2-methylenecyclopropyl)ethanol (equation 294) In the reaction with C-labeled ethylene oxide the addition of TMEDA to the reaction mixture is recommended. ... 

A few experiments have been performed on multiply tritiated molecules containing functional groups. Tritiated ethanol, in which the principal isotopomer is CH2TCHTOH, has been permitted to undergo S-decay in the presence of 0.5 bar of gaseous trimethylamine. At that pressure the ion-molecule collision rate is faster than 10 s The recovered radioactive neutral product is predominantly acetaldehyde, with a barely detectable yield of ethylene oxide (in a ratio > 40 1). As equation 15 summarizes, this implies that nuclear decay produces, for the most part, protonated acetaldehyde, regardless of which tritium expels a /6-particle. 

Common features of the tetrakis(pyridine)silver dichromate oxidations of vicinal and non-vicinal diols and their monoethers, aliphatic aldehydes, a-hydroxy acids (glycolic, lactic, malic and few substituted mandelic acids), and aliphatic primary alcohols in DMSO are = a + h[H+], fractional order in the substrates, = 5.91 (ethane diol), 5.80 (MeCHO), 5.78 (mandelic acid), and 5.85 (ethanol). The solvent effects have been analysed using Taft and Swain multiparametric equations for all the substrates except mandelic acid, for which the Kamlet and Swain multiparametric equation is used. The rate constants for aldehydes correlated with Taft s a values with a negative reaction constant. The rate-determining step for oxidation of aldehydes and hydroxy acids is the transfer of H ion. For diol oxidation, the...
