cm7s; (b) D'AB = 1.609 x 10 cm/s 18.2-6. Estimation of Diffusivity of LaClz and Temperature Effect. Estimate the diffusion coefficient of the salt LaClz in a dilute aqueous solution at 25C and at 35C. Also, calculate the diffusion coefficient for the ions La3+ and C1 at 25C. What percent increase in rate of diffusion will occur in going from 25 to 35C if the same dilute concentration difference is present at both temperatures? Ans. D'AB(35C) = 1.649 x 10-5 cm/s = 10
