1127 K एवं 1 atm दाब CO and `CO_(2)` के गैसीय मिश्रण में साम्यावस्था पर ठोस कार्बन में `90.55%` (भारात्मक) CO है।
`C(s) + CO_(2)(g)ltimplies 2CO(g)`
उपरोक्त ताप पर अभिक्रिया के लिए `K_( c)` के मान की गड़ना कीजिये।

Best answer
माना साम्य पर गैसीय मिश्रण CO+ `CO_(2)` =100 g
गैसीय मिश्रण में CO द्रव्यमान `=90.55` g
`therefore CO` के मोल `=(90.55)/28=3.233`
`CO_(2)` के मोल `=(9.45)/(44)=0.215`
`therefore` आंशिक दाब `=(मोल)/(कुल मोलों की संख्या) xx कुल दाब `
`therefore P_(CO) = 3.233/(3.233 + 0.215) xx 1 = 0.938` atm
`P_(CO_(2)) = 0.215/(3.233 + 0.215) xx 1 = 0.062 atm`
`C(s)+ CO_(2)(g) ltimplies 2CO(g)`
`R=0.0821 L atm K^(-1) mol^(-1)`
`therefore K_( C) = K_(p)/(RT)p^(Deltan) = (14.19)/(0.0821 xx 1127) = 0.153`
