Which reaction proceeds more quickly at 125° C?
A) 54 kcal/mole at 1E+13/sec
or
B) 52 kcal/mole at 1E+12/sec ?
Which one of these reactions proceed more quickly?
A) Gaussian distribution of Ea values
centered at 53 kcal/mole with a distribution parameter of
0.50 kcal/mole and A= 5E+13/sec
or
B) Discrete distribution of Ea values
with 10% at 48 kcal/mole, 20% at 51 kcal/mole, 45% at 52 kcal/mole,
and 25% at 54 kcal/mole with A = 7.5E+13/sec ?
Can you predict the extent of decomposition of for any one of the above reactions at 120° C for 72 hours?
Need help???
Or, at least, do you need the answer quickly? KMod provides the solutions using user described reaction kinetics or by directly reading output from the Kinetics2000 program including result from the:
Results manually input by the user can be saved as parameter files for future reference and comparison to new results either experimental or published.
KMod provides a convenient way of evaluating and comparing reactivities based on kinetic parameters using either laboratory or natural heating rates under isothermal or nonisothermal conditions. Thus, rates of reaction or decomposition can be readily compared as well as the extent of conversion at a given thermal exposure.
If modeling the rate of decomposition matter to form oil and gas, vitrinite reflectance values are also calculated.
The temperatures and maturities at 10%, 50%, Peak, and 90% transformation are also calculated and reported. This permits an assessment of the kinetic data and also permits comparison of results among samples having different A factors. Any variations among the different kinetic models may be evaluated using the KMod program as well.
In addition a graphical display of KMod result files and kinetic parameters can be easily completed using KinGraph.
