K(c) for the reaction N(2)(g)+3H(2)(g)...

`K_(c)` for the reaction
`N_(2)(g)+3H_(2)(g)hArr2N_(3)(g)` is 0.5 at `400K` find `K_(p)`

Text Solution

Verified by Experts

`N_(2_((g)))+3H_(2_((g))) hArr 2NH_(3_((g)))`
Given `K_(C)=0.5`
`T=400 K`
`K_(P)=K_(C) (RT)^(Deltan)`
`K_(P)=0.5xx(0.0821xx400)^(-2)Deltan=-2`
`K_(P)=0.5xx(8.21xx4)^(-2)=0.5xx(32.84)^(-2)`
`(0.5)/(1078.46)=4.63xx10^(-4)`
