QJEEM20Ch02d0: JEE Main 2020 Chemistry - Class 11 JEEM20Ch02d0 Solution: A mixture of one mole each of H 2 , He and O 2 each are…

A mixture of one mole each of H2 , He and O2 each are enclosed in a cylinder of volume V at temperature T. If the partial pressure of H2 is 2 atm, the total pressure of the gases in the cylinder is :

Multiple Choice Options

  • A 14 atm
  • B 38 atm
  • C 6 atm
  • D 22 atm

Step-by-Step Verified Solution

According to Dalton’s law of partial pressure, pi = xi × PT

pi = partial pressure of the ith component

xi = mole fraction of the ith component

pT = total pressure of mixture

⇒ 2 atm = (nH2nH2+nHe+nO2) × pT

⇒ pT = (1+1+11) × 2 = 6 atm
