Hello,

Is it possible to define a model for rate of reaction = k*( [I]^0.5 )*( [M]^1.25 )? it is basically polymerization acrylamide. [I] is the initiator concentration whereas [M] is the monomer concentration. If it is possible then please let me know which model will be used.

Thanks in advance.

Regards,
Sudhanshu Soman

I would not use Comsol at all, but Matlab, for example, its Runge-Kutta algorithms.

If [I] is a constant, defining new variables

T = t*k*[I]^0.5
C = [M]/[M]_0

C(T) = (T/4 + 1)^-4
