Question

Which pair of the gaseous species diffuse through a small jet with the same rate of diffusion at same p and t?

Answer 1

Solution

NONO and ethane diffuse through a small jet with the same rate of diffusion at same PPand TT.
The rate of diffusion is inversely proportional to the square root of molar mass.
Both NONO and ethane have same molar mass (3030).
Hence, both diffuses at the same rate.

Answer 2

NO and C₂H₆ are the gases diffuse through a small jet with the same rate of diffusion at same p and t  :

Explanation:

• Ethane and NO  diffuse thru a small jet with the identical rate of diffusion at identical P and T.

• Both NO and ethane have same molar mass (30).Hence, both diffuses at the same rate.

• The rate of diffusion is inversely proportional to square root of molar mass
• The molar mass of NO = 30 and that of C₂H₆ =30 so, therefore the rate of diffusion is same.

Therefore answer = NO and C₂H₆
