For the reversible reaciton, N_(2(g))+3H_(2(g))hArr2NH_(3(g)) at 500^(@)C, the value of K_(p) is 1.44xx10^(-5) when partial pressure is measured in atmospheres. The conrresponding value of K_(c) with concentration in mole "littre"^(-1), is

Answer»

`1.44xx10^(-5)//(0.082xx500)^(-2)`
`1.44xx10^(-5)//(8.314xx773)^(-2)`
`1.44xx10^(-5)//(0.082xx773)^(2)`
`1.44xx10^(-5)//(0.082xx773)^(-2)`

SOLUTION :`underset(4)(H_(2)+3H_(2))hArrunderset(2)(2NH_(3))`
`Deltan=2-4=-2`
`K_(p)=K_(c)[RT]^(Deltan),K_(p)=K_(c)[RT]^(-2)`
`K_(c)=(K_(p))/([RT]^(-2))=(1.44xx10^(-5))/([0.082xx773]^(-2))`
