Fig. 5. Simulated reaction rate profiles in a 0.356-cm-radius aggregate 48 h after labeling with 99.9 atom % ¹⁵NH⁺₄. Reaction rate profiles were calculated from the time period of 24 to 48 h at each spatial node in the zero-order consumption, finite difference model. Dashed line represents simulation input reaction rate of k_cA = k_pA = 1 µg N cm^-3 d^-1, K_d = 13 cm³ g^-1.
