Please solve correctly and explain if possible

5) The diffusivity coefficient of a substance can be calculated from Fick's Law and is represented in the following equation: -E D = D, exp 11.987 T D = diffusion coefficient, (cm /s] Do = maximum diffusion coefficient E = activation energy of diffusion, (cal/g-mole) T = absolute temperature, [K] 1) What are the units of Do and the constant 1.987? Justify your answer. 2) Derive an equation for D [in /s] where and E can be entered in PR and Btu/b-mole, respectively. 3) What is the maximum diffusion coefficient Do for a D = 2 in /s, E = 1,000 Btu/lb-mole, and T = 180 'R
