Imidazole is a common molecular species in biological chemistry. For example, it constitutes the side chain of the amino acid histidine. The rate constant for the protonation reaction is 5.5 × 10¹⁰ M^–1 s^–1. Assuming that the reaction is diffusion controlled, estimate the diffusion coefficient of imidazole when D(H⁺) = 9.31 × 10^–5 cm² s^–1, r(H⁺) ~ 1.0 Å, and r(imidazole) = 6 Å.Use this information to predict the rate of deprotonation of imidazole by OH⁻ (D = 5.30 × 10^–5 cm² s^–1 and r = ~1.5 Å).
