An experiment is done as shown in diagram then final pressure after stop cock is opened. [Assume reaction : NH_(3) (g) + HCl (g) rarr NH_(4)Cl (s) ]

Answer»

<P>3 atm
`(1)/(3)` atm
1 atm
`1.5` atm

Solution :`NH_(3) (g)`
`N = (PV)/(RT) = (1 XX 22.4)/(0.0821 xx 273 xx 2) = (1)/(2)` MOLE
`HCl (g)`
`n = (PV)/(RT) = (1 xx 44.8)/(0.0821 xx 54.6) = 1` mole
`{:(NH_(3) (g),+,HCl (g),rarr,NH_(4)Cl(s),),((1)/(2),,1,,0,),(0,,(1)/(2),,(1)/(2),):}`
`n_(HCl) = (1)/(2)` mole
`P = (0.5 xx 0.0821 xx 546)/(67.2)`
`P = (1)/(3)` atn
