Answer:

He

Step-by-step explanation:

  • According to the Graham's law of effusion or diffusion, the rate of diffusion of a fixed mass of a gas is inversely proportional to the square root of its density.
  • Therefore, the lighter the gas, the higher the rate of effusion rate since the effusion rate of a gas is inversely proportional to the square root of its molecular mass.
  • In this case, Helium gas is the lightest and thus, it will diffuse faster compared to the other gases.
