Consider the adjacent diagram. Initially, flask  contained oxygen gas at  and 950 mm of Hg, and flask  contained neon gas at  and 900 mm. Finally, two flask were joined by means of a narrow tube of negligible volume equipped with a stopcock and gases were allowed to mixup freely. The final pressure in the combined system was found to be 910 mm of Hg

Which of the following statements concerning oxygen and neon gas is true in the beginning, when the stopcock was just opened?

a)

 moved at faster rate toward flask

b)

 moved at faster rate towards flask

c)

Both  and  gases moves at equal rate

d)

Insufficient information to compare the rate of effusion
