May 26, 2015 at 12:36 comment added Phab I may not understand your problem, but why don't you just write your r eqns as r1 = k1[r, \[Phi]] nH[r] nOH[r] etc?

May 26, 2015 at 11:19 comment added André Oliveira I'm trying to model the chemical abundance of a Mira star as a function of its radius. The temperature t[r_,ϕ_] changes as a function of the star radius and so the rate constants k, as it depends exponentially on the temperature k = α*((t/300)^β)*(Exp[^- γ/T)
May 26, 2015 at 4:51 comment added MarcoB Out of curiosity, What chemical process are you modeling? If I am not misunderstanding, your rate constants change in the course of your process. What causes the change?
