Figure 4: The profile of the normalized concentration of o-quinone product 𝑤 versus the normalized distance 𝑥 . The concentrations were computed using (13) when the parameters 𝜇 2 = 1 0 , 𝛼 1 = 0 . 1 , 𝛼 2 = 0 . 1 and for various values of 𝜇 1 and 𝛿 / 𝐿 . The key to the graph (stacked line) represents (13) and (dotted line) represents the numerical solution. (a) 𝛿 / 𝐿 = 0 , (b) 𝛿 / 𝐿 = 0 . 5 , (c) 𝛿 / 𝐿 = 1 , (d) 𝜇 1 = 0 . 1 .
