Answer:
NO.
Explanation:
The rate of diffusion of gases is inversely proportional to the square root of its density as explained by Graham's law of diffusion i.e
Rate (R) & 1/√(density (d))
R & 1/√d
But the density of a gas is proportional to the molar mass (M) of the gas.
Thus, the above equation can written as:
R & 1/√d
R & 1/√M
This implies that rate is inversely proportional to the molar mass of a gas i.e the lighter the gas, the faster the rate and the heavier the gas, the slower the rate of diffusion.
Now, to obtain the answer to the question, let us determine the molar mass of each gas.
This is illustrated below:
Molar mass of Kr = 84 g/mol
Molar mass of NO = 14 + 16 = 30 g/mol
Molar mass of Ar = 40 g/mol
Molar mass of N2O = (14x2) + 16 = 44 g/mol
Summary
Gas >>>>>>> Molar mass
Kr >>>>>>>>> 84 g/mol
NO >>>>>>>> 30 g/mol
Ar >>>>>>>>> 40 g/mol
N2O >>>>>>> 44 g/mol
From the above table, we can see the lightest gas is NO.
Therefore, NO will escape through the hole in the balloon at the highest rate.
