Question: Extrapolation of binary diffusivity to a very high temperature, a value of DAB = 0.151 cm 2 /s has been reported1 for the system CO2-air

Extrapolation of binary diffusivity to a very high temperature, a value of DAB = 0.151 cm²/s has been reported1 for the system CO2-air at 293K and 1 atm. Extrapolate DAB to 1500K by the following methods:

(a) Equation 17.2-1.

(b) Equation 17.3-10.

What do you conclude from comparing these results with the experimental value 1 of 2.45cm²/s?
