Graham's law Q
« on: July 23, 2008, 05:12:46 PM »
 if for example a container holds CH4 and SO2. and I want to find the relationship between their speeds using Grahams law, if Vs is SO2's speed and Vm is CH4's speed then I think the answer should be Vs=2Vm  because methane is lighter so it's traveling twice as fast a SO2 but the book says the correct answer is Vm=2Vs.....I don't understand whyyyy? make no sense to me at all :-\

please help thanks

Vm=2Vs means that methane is twice as fast as sulfur dioxide, so it is exactly what you expect.
