Neon (Ne) gas effuses faster than Argon (Ar) gas.
The rate of effusion of a gas is inversely proportional to the square root of its molar mass. Since the molar mass of neon (20.18 g/mol) is lower than that of argon (39.95 g/mol), neon gas effuses faster.
To determine how much faster neon effuses compared to argon, we can calculate the ratio of their effusion rates using the formula:
Rate of effusion of A / Rate of effusion of B = √(molar mass of B / molar mass of A)
Let's substitute the values for Neon (A) and Argon (B) into the formula:
Rate of effusion of Ne / Rate of effusion of Ar = √(39.95 g/mol / 20.18 g/mol)
Calculating this, we get:
Rate of effusion of Ne / Rate of effusion of Ar ≈ 1.41
Therefore, neon gas effuses approximately 1.41 times faster than argon gas.
Which gas effuses faster, Ne or Ar, and how much faster?
