Each of three identical 15.0-L gas cylinders contains 7.50 mol of gas at 295 K.Cylinder A contains Ar,cylinder B contains Cl₂,and cylinder C contains N₂.According to the kinetic molecular theory,which gas has the highest average speed? A)Ar B)Cl₂ C)N₂ D)All have identical average speeds

Question

Quizplus · Accepted Answer

According to the kinetic molecular theory, the average speed of gas molecules is inversely proportional to the square root of their molar mass. N₂ has the lowest molar mass among the gases, so it has the highest average speed.
