Give the mathematical expression for the equilibrium constant `(K_(c) " and " K_(p))` for the reactions.
`(i) H_(2)(g) + I_(2)(g) hArr2HI(g)`
`(ii) N_(2)(g) +3H_(2)(g) hArr 2NH_(3)(g)`
`(iii) PCl_(5)(g) hArr PCl_(3)(g)+Cl_(2)(g)`

Text Solution

Verified by Experts

`(i) " "K_(c) =([HI]^(2))/([H_(2)][I_(2)]) , K_(p) = K_(c)(RT)^(Deltang)=K_(c)(RT)^(2-2)=K_(c)`
`(ii)" "K_(c)= ([NH_(3)]^(2))/([N_(2)][H_(2)]^(3)), K_(p)=K_(c)(RT)^(Deltang)=K_(c)(RT)^(2-4) = K_(c)(RT)^(-2)`
`(iii) " "K_(c) = ([PCl_(3)][Cl_(2)])/([PCl_(5)]), K_(p)=K_(c)(RT)^(Deltang) = K_(c)(RT)^(2-1)=K_(c)(RT)`
