1.	The degree of dissociation is `0.4` at `400 K` and `1.0` atm for the gaseous reaction `PCl_(5) hArr PCl_(3)+Cl_(2)` assuming ideal behaviour of all gases, calculate the density of equilibrium mixture at `400 K` and `1.0` atm (relative atomic mass of P is `31.0` and of Cl is `35.5`).
Answer» `{:(,PCl_(5)(g),hArr,PCl_(3)(g),+,Cl_(2)(g)),("Initial",1,,0,,0),("At equilibrium",(1-0.4),,0.4,,0.4):}` Total moles at equilibrium is `1-0.4+0.4+0.4=1.4` `PV=nRT` or `V=(nRT)/(P)=(1.4xx0.0821xx400)/(1)=45.976 L` Density =`("Mass")/("Volume")` `=208.5/45.976(("No change in mass"),("during reaction"))=4.54 g L^(-1)`
