<u>Answer:</u>
<u>For A:</u> The average molecular speed of Ne gas is 553 m/s at the same temperature.
<u>For B:</u> The rate of effusion of gas is
<u>Explanation:</u>
<u>For A:</u>
The average molecular speed of the gas is calculated by using the formula:
OR
where, M is the molar mass of gas
Forming an equation for the two gases:
.....(1)
Given values:
Plugging values in equation 1:
Hence, the average molecular speed of Ne gas is 553 m/s at the same temperature.
<u>For B:</u>
Graham's law states that the rate of diffusion of a gas is inversely proportional to the square root of the molar mass of the gas. The equation for this follows:
Where, M is the molar mass of the gas
Forming an equation for the two gases:
.....(2)
Given values:
Plugging values in equation 2:
Hence, the rate of effusion of gas is
