Problem $1$: Predict the diffusivity of the following gas mixtures using Fuller$-$Schettler$-$Giddings correlation:

a$.$ Carbon sulfide $(C{S}_2)$ in air at $35C$ at $1$atm

b$.$ Toluene in air at $1$atm pressure and $30C$

c$.$ Aniline in air at STP

Problem $2$: Calculate the diffusivity of acetone in air at STP $($standard temperature pressure$)$ using FullerSchettler$-$Giddings correlation. If the gas mixture temperatureis increased to $25C$ atconstant pressure, estimate the gas diffusivity.
