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^


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.
