Coupled ODE for chemical reaction

  1. Apr 7, 2007 #1
    I have a problem.. for a reaction

    A + B --> C

    how do i generate 3 coupled differential equations so that i can sole this using MATLAB ?
    it is given that rate = kAB

    thnks!

    Solve for what? Can you be more specific?

    I'm not sure what you're asking for, but i think its the material balance to each component in a Batch Reactor, if thats the case, the solution is the following:

    For component A:

    [tex]\frac{dC_{A}}{dt}=-kC_{A}C_{B}[/tex]


    component B:

    [tex]\frac{dC_{B}}{dt}=-kC_{A}C_{B}[/tex]


    and component C:


    [tex]\frac{dC_{C}}{dt}=kC_{A}C_{B}[/tex]



    I think i have done this right.

    It's now easy to implement this in Matlab and get the [tex]C_{i}(t)[/tex] plots.

    Take care.

    (sorry, there was a mistake in the MB, i have changed it now)
