This is grade-12/college-level but if you're curious I will show you below. So for a first order reaction -- we have the reaction equals the rate constant times the concentration of the (only) reactant --> R = k [A] 1. Then we choose to re-write R as -Δ [A]/Δt. and we get -Δ [A]/Δt = k [A] 2. Then we bring -Δt to the right side. flowhouse.cz

"Webresolution x requires a simultaneous reduction in the time-step t by a factor of four in order to maintain numerical stability. Certainly, the above constraint limits us to absurdly small time-steps in high resolution calculations. The next point to emphasize is the numerical dispersion. Indeed, let us compare the exact dispersion relation for Eq. " - Solve ivp for concentration and time reaction
