(Multiple Choice) List the gases H2O, He, HCI, BrF, and NO2 in order of increasing average molecular velocityat 25°C.1. Rates of effusion:BrF< H20 < HC1 < NO2 < He2. Rates of effusion: BrF < He < HC1 < H2 < NO23. Rates of effusion: He < BrF < HC1

Sagot :

The average molecular velocity can be defined as follows:

[tex]v_m=\sqrt[]{\frac{3RT}{M}}[/tex]

Where,

R is a constant

T is the temperature

M is the molar mass

If we assume that the temperature is the same for all gases, the velocity will vary according to its molar mass. We see that the molar mass is inversely proportional to the speed, the greater the mass of the gas, the slower it will move. Therefore we are going to determine the molar mass of the gases:

Therefore, the order according to the average velocity will go. We must organize from the largest molar mass to the smallest molar mass.

BrF

The answer will be 6. Option
