With Arrhenius temperature effect
2025.Apr.22 19:05:07
Final t Final t for integration.
Temperature Temperature (K).
Initial values Initial values.
A, Ea Arrhenius A and Ea.
Method        Method of integration.
x & y axes bounds (a = automatic) Lower, upper bounds for x, upper y in plot.
Points N. of plot points.
Show values Show graph coordinates.

Solves the system of ODEs in Fig. 1. With the given data, this system depends strongly on T, through rate = A exp[Ea ⁄ (R T)], R = 8.314 .

ODEs Fig. 1

Shows the graphical result. Other suggested data: (A, Ea) = (1e+5, 30e+3)

Keywords: Arrhenius; kinetics; temperature dependence.
