Effusion is the escape of a gas through a small hole.

Graham Law states that the speed of effusion is inversely related to the square root of its molar mass:

effusion speed = K * 1 / √ molar mass)


=> effusion speed of gas A        √(molar mass of gas B)
     ---------------------------------  =  ----------------------------------
     effusion speed of gas B         √(molar mass of gas A)


=> efussion speed of Ne          √(83.8)
     -----------------------------    =    ----------    = 2.04
     effusion speed of Kr            √(20.18


=> effusion speed of Ne = 2.04 * effusion speed of Kr.

Answer:

According to the Graham's law equation, the effusion rate of neon divided by the effusion rate of krypton is equal to the square root of the molar mass of krypton divided by the molar mass of neon. Doing the calculation, you find that neon effuses 2.03 times faster than krypton.
