Question

Organize the following gases in order of their rates of diffusion, from slowest to fastest ; oxygen, ammonia, hydrogen, carbon dioxide

Answer 1

Answer:

Explanation:

Chlorine

Neon is the fastest. Chlorine is the slowest. We must assume that all these gases are at the same temperature.

Answer 2

The order from slowest to fastest :

Carbon dioxide , oxygen,Ammonia, Hydrogen.

As the carbon dioxide has greatest molecular mass then it is diffuse at low . Further oxygen and then Ammonia and last is Hydrogen has smallest molecular mass then it is diffuse at fastest rate .

Explanation;

Diffusion of gas :

It is defined as the diffusion of a gas is inversely proportional to the square root of the molar mass of given gas .

The molar mass

• carbon dioxide= 44 gm/mol
• Hydrogen = 2 gm/mol
• oxygen = 32 gm/mol
• Ammonia=17 gm/mol

The greater the relative molecular mass of a molecule ,the slowest it diffuse .Diffusion is depend on the molecular mass , temperature and concentration gradient .
