ABSTRACT
Solution As seen, this is a nonelementary reaction and can be a first-or second-order reaction.
Assuming a first-order reaction rate, we calculate the specific rate constants for different temperatures, using Equation 5.18. Results are shown below:
k= 0.693 t1/2
Thus, Table 11.1 presents the values of k1 varying with temperature:
ever, between 50◦C and 200◦C, the experimental data fit very well in the Arrhenius plot (Figure 11.2). From this figure, we calculate the energy of activation equal to 23,400 cal/mol. In conclusion, experiments were carried out under kinetic conditions in this temperature range. However, for higher temperatures, there are diffusion effects.
ER.2 Demonstrate that the reaction rate of the product for an autocatalytic reaction:
