Question

Equal masses of SO2 CH4 and O2 are mixed in an empty container at 298 K, when total pressure is 2.1 atm. The partial pressure of CH4 in the mixture is (A) 0.5 atm (B) 0.75 atm (C) 1.2 atm (D) 0.6 atm

Tardigrade Admin · Accepted Answer

Let w g of each SO2 CH4 and O2 are mixed. ∴ Mole fraction, XCH4 = (nCH4/nSO2 +nCH4 +nO2) - ((w/16)/(w)64 +(w)16 +(w/32) = (4/7) (Molecular weight of SO/2) = 64 u, CH4 = 16 u, O2 = 32 u) Partial pressure of CH4 PCH4 = Mole fraction × Total pressure(4/7) × 2.1 = 1.2 atm
