For any chemical reaction the catalyst or multipletts ensure that lower reaction temperature and lower pressure is enogh to start and maintain reactions
Reactions are normally modelled in thermodinamical equations
In this eqzuations higher energy is needed than with catalysts where do I find scientific model to enter the catalyst parameter into the equation?
What does it mean "thermodinamical equations"?
Maybe you mean thermodynamic equations.
And additionaly, the reactions (their course) are modelled using mass and energy balance equations.
Regards,
Thank you are right it is thermidynamic equation
Still the equation is changed when catalyst is involved
The reaction thermodynamics does not depend on catalyst. A catalyst redirects the reaction through a pathway with lower activation parameters. Probably, you are asking about a kinetic model.
Briefly, the equilibrium position and thereby equilibrium conversion does not change by employing a catalyst. Catalysts just provide alternative mechanisms that do have lower activation energy. This lowering in activation energy speeds up the rate of attainment of equilibrium. Kinetic modeling of a reaction system involves energy balance equations (in case of non-isothermal or adiabatic reaction system) as well as mass balance equations that in turn includes the intrinsic rate equation for the system. The rate constant in the intrinsic rate equation captures the effects of temperature and catalysts.
So we continue to guess what the questioner meant.
It is worth noting that the questioner did not specify which thermodynamic equation / equations wanted to use - and there are many.
It would also be necessary to specify the type of reactor.

Continuing:
We do not know whether the reaction / reactions is reversible or not.
We also do not know under what conditions the process is going, ie isothermal, adiabatic or non-isothermal. Thermodynamic considerations, on the other hand, do not necessarily have to involve chemical equilibrium, only estimation of the enthalpy of chemical reaction / reactions. etc. etc.

Miroslaw, this is very common in Q&A forum that the person posting a question is not very interested in answers. Vague questions are also very common.
I fully agree with Your opinion. I also think that asking questions sometimes does not understand what they are asking.

Any reaction, any catalyst, any model, lower temperature and pressure .......
It is not enough.
