`K_(p)` के मान से निम्नलिखित में से प्रत्येक साम्य के लिए `K_( c)` का मान ज्ञात कीजिये-
(i) `2NOCl(g) ltimplies 2NO(g) + Cl_(2)(g), K_(p) = 1.8 xx 10^(-2)` at 500 K
(ii) `CaCO_(3)(s) ltimplies CaO(s) + CO_(2)(g), K_(p)=167` at 1073 K

Explanation

(i) `2NOCl(g) ltimplies 2NO(g) + Cl_(2)(g)`
`therefore Deltan=3-2=1, R=0.0821 L " atm " mol^(-1) K^(-1)`
`therefore K_( c) = K_(p)/(RT)^(Deltan)= (1.8 xx 10^(-2))/(0.0821 xx 500)^(1)=4.38 xx 10^(-4)`
(ii) `CaCO_(3)(s) ltimplies CaO(s) + CO_(2)(g)`
`therefore Deltan=1-0=1, R=0.081 L " atm " mol^(-1)K^(-1)`
`therefore K_( c) = K_(p)/(RT)^(Deltan)=167/(0.0821 xx 1073)^(1) = 1.89`
