a' moles of PCIs undergo thermal dissociationas-PCl PCI3 +CI2, the mole fraction of PCat equilibrium is 0.5. The total pressure is 2.0atmosphere. The partial pressure of Cl2 atequilibrium is(A) 2.5(C) 0.5(D)

Answer»

just multiply mole fraction of PCl2 with the total pressure to get p(PCl2) which is the partial pressure of PCl2...since, at equilibrium p[PCl2] = p[Cl2]there fore answer is 1

The answer is Option B.
