I made the following code ,but dont know what i have to change to make it run.
syms y(t,z)
U=10;
E_l=1e-8;
cyanide=159;
oxygen=8;
r=0.706e-3*(cyanide^1.38)*(oxygen^0.161)*(y-0.17)^2.19
ode = -(diff(y,t))-U*(diff(y,z,1))+E_l*(diff(y,z,2))-r == 0
ySol = dsolve(ode)
Thanks in advance for the help.

PDEs cannot be solved with the symbolic toolbox.
Use "pdepe" as numerical solver instead.
