Example 3.1. In certain cases, a reaction can proceed in either direction. For example, in the hydrogenation of ethylene (C2H4) to ethane (C2H6), a proposed mechanism is C2H4+H2- C2H6, H2 2H C2H4 + HC₂H C2H5 + H C2H6 where the first reaction can proceed in either direction. According to the law of mass action, we can model this mechanism with the following system of ODE, d[H2] =-k₁[H2]+k-1[H]2 dt d[H] 2k₁ [H2] 2k1[H]-ka[C₂Ha][H] - k3[C₂H][H] dt dC₂H] =-k₂[C₂H][H] dt d[C₂Hs] - ka[C₂Ha][H] ka[C₂Hs][H]. dt
