Question 3 Consider the diffusion of a spherical particle in a liquid: D is the diffusion coefficientI r is the particle radius; the liquid has viscosity n and temperature T. Which graph is INCORRECT? D D D A B C O graph A O graph B O graph C 0 all of the graphs are correct Question 4 You are measuring the molar mass of two types of protein molecules through a diffusion experiment. Separate solutions of protein A and B in salt water are studied, and the diffusion coefficients of both molecules are found to be the same - however. you realize after the experiment that the viscosity of sample B was twice as great as that of sample A. Which protein has the larger molar mass? 0 they have the same molar mass 0 the experiment needs to be redone before the molar masses can be determined
