Answer

Molecular oxygen effuses faster at the same temperature

Work Step by Step

rate O2/rate Ar = square root of (40g/mol Ar / 32g/mol O2) Plug in molar mass on right side of equation, equation is taken from Graham's law 1.25x faster Molecular oxygen is 1.25 times faster than atomic argon, so therefore:
