Question
Q3. Choose a single answer. Show steps. 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? Pl
