Phosphorus pentachloride dissociates as follows, ina closed reaction vessel, PC1_(5(g))hArrPC1_(3(g)) + C1_(2(g)) If total pressure at equilibrium of the reaction mixture is P and degree of dissociation of PC1_(5) is x, the partial pressure of PC1_(3) will be:

Answer»

`((x)/(x-1))P`
`((2x)/(1-x))P`
`((x)/(x-1))P`
`((x)/(1-x))P`

Solution :`{:(PCl_(5(G))hArrPCl_(3(g))+Cl_(2(g))),(1""0""0),((1-x)""x ""x):}`
`therefore"Partial pressure of" PCl_(3)=((x)/(x+1))P`
