It is known that the mass flux follows Fick's first diffusion law (given in first question). Employ the following data to estimate D. Calculate coefficient of determination using Stand S!!! Use the data below 1.5 2.5 4.5 6 8.6 10 dc/dx (g/cm^) Mass flux (g/cm s) 5.23 x 10-4 4.5 x 10-4 3.14 x 10-4 2.35 x 10-4 1.31 x 10-4 7.8 x 10-5
