The diffusivity of Argon in No at 20 °C and 1 atm pressure is 0.194 cm³/s. What would you

expect the diffusivity of N: in Ar to be at 50 °C and 2.5 atm? Use the Chapman correlation.

Does increasing the temperature or increasing the pressure have more effect on the

diffusivity? Please comment

A) 0.194 cm³/s

B) 0.442 cm³/s

D) 0.535 cm³/s

E) 0.555 m³/s

F) 0.535 m³/s

G) 0.442 m³/s

H) 0.09 cm³/s

) 0.09 m²/s
