1.	Estimate the diffusion coefficient of carbon monoxide through air in which the mole fractions of each constituents areO 2 = 0.18N 2 = 0.72CO = 0.10The gas mixture is at 300 K and 2 atmosphere total pressure. The diffusivity values areD CO = 18.5 * 10 -6 m2/s at 273 K, 1 atmD CN = 19.2 * 10 -6 m2/s at 288 K, 1 atmThe subscripts C is carbon monoxide, O is oxygen and N is nitrogen
A.	10.29 * 10 -6 m2/s
B.	18.5 * 10 -6 m2/s
C.	17.5 * 10 -6 m2/s
D.	13.5 * 10 -6 m2/s
Answer» B. 18.5 * 10 -6 m2/s
