Determine the value of the gas diffusivity of carbon tetrachloride in air at 50C and 1.7 bars using Hirschfelder's equation and using Fuller, Schettler, and Giddings Correlation. Assuming Hirschfelder's equation is more accurate, what will be the % error in the value calculated using Fuller, Schettler, and Giddings Correlation? Problem 3 Determine the value of the gas diffusivity of carbon tetrachloride in carbon dioxide at 50C and 1.7 bars using Hirschfelder's equation. Using the calculated value and the results of problem 2, use Wilke correlations to calculate the diffusivity of carbon tetrachloride in a mixture containing 55 mole % air, 35% carbon dioxide and the balance is ammonia
