Which gas would have the slowest rate of diffusion, assuming that all gases are at the same temperature?
Iteru [2.4K]

Answer: radon (atomic mass 222 amu

Explanation:

To calculate the rate of diffusion of gas, we use Graham's Law.

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows:

\text{Rate of diffusion}\propto \frac{1}{\sqrt{\text{Molar mass of the gas}}}

atomic mass of krypton= 83.8 amu

atomic mass of argon= 39.95 amu

atomic mass of xenon = 131.3 amu

atomic mass of radon= 222 amu

Thus as atomic mass of radon is highest, its rate of diffusion is slowest.

The boiling point of liquid oxygen is 90.2 k at atmospheric pressure. (a) what is this temperature on the celsius scale?
steposvetlana [31]
Oxygen  is a  liquid  under   one atmosphere.  the  boiling  point  of  a  substance is the temperature  at  which  vapor  pressure  of a  liquid  is  equal  to  the  pressure  of  the  surrounding liquid. the boiling  point  of  oxygen  at  this  case  is  90.0k. Therefore  the  temperature of oxygen is 90-273=  -183  celsius  scale
