Problem $1$: Diffusivity Coefficients.

a$.$ Carbon monoxide $(100\%)$ diffuses through itself at $20C$ and $1$atm. Assume ideal gas.

b$.$ Carbon monoxide $(10\%)$ diffuses through nitrogen $(90\%)$ at $20C$ and $1$atm. Assume ideal gas.

c$.$ Carbon monoxide $(10\%)$ diffuses through oxygen $(20\%)$ and nitrogen $(70\%)$ at $20C$ and $1$atm. Assume ideal gas.

d$.$ Carbon monoxide $(10\%)$ diffusing through nitrogen $(90\%)$ at $100C$ and $10$atm. Intramolecular forces cannot be neglected $($do not assume ideal gas$).$

e$.$ Making Kool$-$Aid $$ by dissolving sugar $($glucose$,R_O$~$=10)$ in water at $20C$ and $1$atm.

f$.$ Diffusion of dilute gelatin $($polymer$)$ in water. Radius of gyration of gelatin is $15nm.$

g$.$ Mountain Dew ${?}^{}+$ Brita: Diffusion of yellow #$5$ into activated carbon with $80nm$ diameter pores that are $1\mathrm{.}5mm$ long.
