Energy Balance with Reaction

Показать описание

Two methods are shown for computing a change in enthalpy when there are reactions. The first method, path approach, is shown for a simple A to 2B reaction. The second method, heat of formation approach, is shown for ammonia oxidation in a two reaction sequence.

It's actually help in my career of Mathematical Modeling with Chemical Equations

Thank you for this video! It was very helpful. I appreciate what you are doing!

thank you for such amazing presentation on this topic. I got a question, so these Cp values with their coefficients are used when dealing with conditions that satisfy ideal gas behavior but the other two stream conditions in the example, air & outlet, were at non ideal conditions why it is still applied? I wonder if I can use this method in a process with conditions at 20 bar and 900C plz help thank you!

Dear sir: do the same technique apply to calculate the heat of formation for surface reaction? Where the two reactants (one is gas and another is metal surface), both at different temperatures, react and form metal oxide and residual gas as products. In this reaction, what would be the typical temperatures of products?

on the second problem, what if we have different pressures entering and exiting? what would it change in the calculations?

hello sir, is it still can be applied to a single reaction ?

Sir what will be effect of pressure on the cp coefficients.sir I have ok one doubt.The coefficients u are considered are only valid for low pressures but u r pressure is 8 bar it's not low.what will be the effect of pressure in the heat of recation

i know im late, but if the inlet feed has multiple species(ie: air contains co2 and other), is it still the same calculation for Q? do i need to consider other stuff as well?
