The pressure in a vessel that contains pure oxygen
Asked by admin @ in Chemistry viewed by 291 People
A pressure in a vessel tht contained pure oxygen dropped from 2000 torr to 1500 torr in 40min.
Answered by admin @
Molar ratio of a mixture of oxygen and another gas is 1 : 1 at a pressure 4000 mm,
Partial pressure of each gas = 2000 mm Hg.
The decrease in the pressure of oxygen after 1 minutes
= 500/40 = 12.5 mmHg
The decrease in the pressure of oxygen after 74 minutes
P = 12.5 * 74 = 925 mm of Hg
The pressure of oxygen
= 2000 – 925 = 1075 mm of Hg
Let the rate of diffusion of other gas is
Rn / RO2 = (32 /79 )1/2
P = P0 * R^2
Decrease in pressure for the other gas =925 * 32/79
= 374.68 mm of Hg
Pressure of the other gas
= 2000 – 374.68 mm = 1625.31 mm of Hg
Molar ratio = Moles of other gas/Moles of O2
= 1625.31/1075 = 1.51/1
