Predict the gas phase diffusion coefficient for hydrogen iodide at $300$K and $2\mathrm{.}0$ bar, using the collision diameter $($collision diameter for HI is $0\mathrm{.}530$ nm$).$ Also predict its thermal conductivity coefficient and viscosity coefficient under these conditions. How does the viscosity coefficient change if the pressure increases to $20\mathrm{.}0$ bar? How does the viscosity coefficient change if the temperature increases to $600$K$?$
