1.	The degreeof dissociation is 04 at 400 K and 10 atm for the gaseous reaction PCl_(5) hArr PCl_(3) + Cl_(2). ,brgt Assming ideal behaviour of all the gases , calculate the density of the equilibrium mixture at 400 K and 10 atmosphere . ( Atomic mass of P = 310 and Cl = 35*5)
Answer» SOLUTION :` {:(,PCl_(5),hArr,PCl_(3),+,Cl_(2)),("At equilibrium",06,,04,,04 "moles"):} ` Average molecular MASS of the mixture` ( 06(31 + 5 xx 355 ) + 04 (31 + 3 xx 355)+ 04 (2 xx 35 5 ))/( 06 + 0 4 + 04 )` ` =( 1251+ 55 + 426)/ (14)=148 92` For ideal gases ,`PV = nRT = w/M RT or PM = w/V RT= d RT ` `:.d= (PM)/(RT)= (1xx 148* 92 )/(0* 08205 xx 400 )= 4* 5374 g L^(-1) `
