Activation energy refers to the pre-factor
Thread Content
Do any of you know what the activation energies and pre-exponential factors are for the reactions of CO with H2, and CO2 with H2? Thank you! ! !
Look up some information. Don’t handle this thing carelessly; if the basic data is incorrect, everything else will be wrong as well.
Reply to 2# *amingteda Okay, thank you!
The activation energy and pre-exponential factor can be determined by using the equations of chemical reaction kinetics, along with laboratory data—specifically, the relationship between the concentrations of reaction components and time. By fitting these data to find a linear relationship, the reaction order can be identified, and thus the desired values can be calculated； For knowledge on this topic, please refer to \"Chemical Reaction Engineering\" and \"Physical Chemistry\".
Your question: What are the activation energies and pre-exponential factors for the reactions of CO with H2, and CO2 with H2? There is no specific relationship; it’s generally quite certain.
Reply 1# king*n1986: The pre-exponential factors and activation energies for the reactions of CO, CO2, and H2 generally need to be determined through regression analysis of reaction kinetics data obtained from experiments; moreover, different experimental conditions yield varying results. If experiments are not conducted, the corresponding parameter values can also be found in literature. Many publications on methanation kinetics contain kinetic data; taking a look at them might be helpful to you.
