Equal numbers of moles of three gases are mixed in a 20L container at 25 C. If the container has a pinhole leak, what is the proper order of the partial pressures of the gases after 2 hours?
A. CO2>H2>CH4
B.H2>CO2>CH4
C. CO2>CH4>H2
D.H2>CH4>CO2
E.CH4>CO2>H2
Homework Answers
As all the gases are at same temperature and pressure and same number of moles .as we know rate of effusion depends upon molar mass of gas.
Order of molar masses gas,
H2<CH4<CO2
Hence order of partial pressure of gases
CO2>CH4>H2
(C) is correct option.
