Question

Highest partial pressure The molecular view of a gaseous mixture is shown. Arrange the gases in the mixture from highest partial pressure to lowest partial pressure. He -CO, CI CO2 - He N, CI, Lowest partial pressure Answer Bank

Answer 1

No. of molecules of con=5 No. of molecules of N2 = 6 No. of molecules of ch = 7 No. of molecules of the = 10 Total no. of molecules = 28 Dantial pressure = fraction of & Tuted Pressure a particular molecule As total pressure is constant partial pressure is directally proportional to the fraction of molence po = 5 x Ptotal w = 5 x P total þch = 7 & Ptotal 28 28 28 P He = 10 x P total

Ptotel is same for all and is also same so partial pressure proportional to No. of molecules Highest partial pressure denominator 28 is directally He ich I N2 CO₂ lowest partial pressure
