Q. According to Graham's Law, how does the rate of effusion of a gas relate to its molar mass?
A.
Inversely proportional
B.
Directly proportional
C.
Equal
D.
Unrelated
Solution
Graham's Law states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass.
The ideal gas law is expressed as PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature.
