The rate coefficients for gas-phase reaction of trifluoroacetic acid (TFA) with two Criegee intermediates, formaldehyde oxide and acetone oxide, decrease with increasing temperature in the range 240–340K. The rate coefficients k(CH2OO + CF3COOH)=(3.4±0.3)×1010cm3s1 and k((CH3)2COO + CF...

When a multi-stage reaction occurs, the rate of the reaction is taken to be that of the slowest step in the reaction mechanism. The rate of a reaction has been found experimentally to depend upon certain factors such as temperature (all reactions); concentration (nongaseous systems); pressure...
Kinetic analysis showed that (i) temperature dependence of the reaction rates of all different aeration mode composting tests clearly followed the Arrhenius equation; (ii) the degradation of organic solids could be quantitatively predicted using the first order reaction model; and (iii) extent of ...
Liquid-phase and gas-phase reaction rates and evaporation rate were then calculated and plotted against test time to illustrate their temporal functionalities. Composite plots of the test fluids were made in both global-rate and specific-rate forms, which are then used jointly to explain a number...

The rate constants of the radical–radical reaction OH(X)+NH(a)→products and the radical–molecule reaction OH(X)+HN3→products were determined in a quasistatic laser photolysis cell at room temperature and a total pressure of 20 mbar. The radicals OH(X) and NH(a) were generated by exci...
