Calculate the Ratio of Effusion Rates for Ar and Kr

Understanding Graham's Law of Effusion

Graham's Law of Effusion states that the rate of effusion or diffusion of a gas is inversely proportional to the square root of its molar mass. Effusion is the process by which gas molecules escape through a small hole into a vacuum. Diffusion is the mixing of gases. Both processes are governed by the same fundamental principle relating to molecular speed and mass.

The law can be expressed mathematically as:

Rate₁ / Rate₂ = √(M₂ / M₁)

Where:

  • Rate₁ is the rate of effusion of gas 1
  • Rate₂ is the rate of effusion of gas 2
  • M₁ is the molar mass of gas 1
  • M₂ is the molar mass of gas 2

In this calculator, we will focus on calculating the ratio of effusion rates for Argon (Ar) and Krypton (Kr). We will use their known molar masses to determine how much faster or slower one gas effuses compared to the other under the same conditions.

Molar Masses:

  • Argon (Ar): Approximately 39.95 g/mol
  • Krypton (Kr): Approximately 83.80 g/mol

Effusion Rate Ratio Calculator (Ar vs. Kr)

This calculator determines the ratio of the effusion rates of Argon (Ar) and Krypton (Kr) based on their molar masses using Graham's Law.
