Hey Admins and other forumer's,
Im having issue with inputting 3 different ODE's coding.
My main purpose is to plot a graph of conversion against weight of catalyst taking in consideration of the Temperature and Pressure Drop. It is a design of packed bed reactor with tubular's.. The main reaction is water gas shift reaction..

dx/dw=-ra/fao
where my Rate=k*eps(-Ea/RT)*(pH20^a)*(pCO^B)*(pC02^c)*(pH2^d)*(1-B)
a=0.72
b=0.17
c=-0.19
d=-0.49
B=(pC02*pH2/(pC0*Keq*pH20))
Ea=81.6 kj/mol
Keq=15.7

dy/dw=(-alpha/2y)(T/T0)
y=P/P0 (Fogler's)

dT/dW= not really sure

Well i tried to do it in matlab..Did it half way and just blanked out..Dont know how to continue..Hope i could get some assistance in it..cant seem to upload matlab files..pasted it into word.

Bali: If you are indeed using Fogler's book, you will find the generalized expression for dT/dW in the textbook. I am going to help you out here this once, please see the link below:

I believe if you actually did a google search, you would have found the answer. And when you say you have problems, please also tell us what kind of problems you are facing.
