Calculate the diffusion coefficient for the protein cytochrome c in aqueous solution assuming sphericity and using the Stokes-Einstein equation at 25degree C. The hydrodynamic radius is R =19.0 Angstroms. The viscosity of water is 1.00 cP = 0.00100 kg/m-s. D_cytc =__m^2/s. If the critical reaction distance is the sum of their radii, what value is expected for the Smoluchowski theory second order rate constant for a diffusion controlled reaction between two cytochrome c's? k_d = Lmol^-1s^-1 What would be the...
