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)
