Question

4 mol of PCl5 is heated at constant temperature in a closed
container if degree of dissociation of pcl5 is 0 5 then calculate
the total number of moles at equilibrium ?

Dear Student,

PCl5   ↔    PCl3  +   Cl2Initial            C                   0              0             At equil
   C(1-α)           Cα           CαTotal number of moles at equilibrium = C(1-α)+Cα+Cα=C(1+α)Here, α= 0
5C=4Therefore, Total number of moles= 4(1+0
5)=4(1 5)=6 mol
