Question

the rate at which a substance through a semipermeable membrance is determined by the diffusivity D(cm^2/s)of the gas . D varies the membrance temperature T(K) according to the arrhenius equation D=D0exp(-E/RT) where D0 = the preexponential factor, E=the activiation energy for the diffusion, R=1.987cal/(mol.k) diffusitivities of co2 in a fluorosilicons rubber tube are meauredat several temperature , with the following results: T(K) 347.0 , 374.2, 396.2, 420.7, 447.7, 471.2 D(cm^2/s*10) 1.34, 2.50, 4.55, 8.52, ,14.07,19.99 ( so that D =1.34*10^(-6)cm^2/s) (a) what the are the unites of D0 and E? (b) how should the dara be plotted to obtain line on the rectangular coordinate ? (c) plot thedata in the manner indicated in part (b), and determine D0and E from the resulting line
