Therefore, the times that analogous blends reach a given force can be used to estimate reaction rate constant ratios.
Some mathematical models have addressed the effects of energy emission corrected with cloudiness factors, the specific month of experimentation and the amount of total global incident radiation (9-11); however, the effects of increased temperature have not been considered in mathematical models of the kinetic law and reaction rate expressions.
mol-1 and the reaction rate was very sensitive to the temperature in the range of 13-35 degC.
In the current work, the reaction rate was modified by adjusting the reactant powers.
Where, k is the reaction rate constant, R is the gas constant, T is temperature, A is Arrhenius constant and E or [E.
Determination of reaction rates in micellar is usually based on the pseudophase mode [1], which treats aqueous, organic, and/or surfactant components of the solvent medium as constituting distinct phases in which reaction occurs and between which reagent and product are distributed in accordance with conventional laws of kinetic and mass transfer.
Equation 1-3 show the mechanism of reaction, equation 4 is the Langmuir Hinshelwood equation for steady state condition, equation 5 is the reaction rate equation whereas equation 6 is rate constant equation and equation 7 shows the integrated model.
