(a) Simulated concentration profiles of S (solid line), R (dashed line) (a); S₂ (solid line) R₂ (dashed line) (b); and RS (solid line) and SR (dashed line) (c); for model (17-27). Enantiomeric excess ee = ([R] - [S] + [R*] - [S*] + 2[R₂] - 2[S₂])/c for c = 2, k₁ = k₂ = k₃ = k₆ = k₇ = 1, k_-1 = k₈ = k₉ = k₁₀ = k₁₁ = 0.1 and k₄ = k₅ = 100. Initial conditions: [S] = 1.9, [R] = 0.1 and concentrations of other compounds equal to zero.
