Question

At `27^(@)C, K_(p)` value for the reaction
`CaCO_(3)(s) hArr CaO (s) + CO_(2)(g)`, is 0.1 atm. `K_(C)` value for this reaction is
A. `4 xx 10^(-3)`
B. `6 xx 10^(-3)`
C. `2xx 10^(-3)`
D. `9 xx 10^(-3)`

Answer 1

Correct Answer - A
`K_(p) = K_(C) (RT)^(Deltan), Deltan = 1`
`K_(c) = (K_(P))/(RT) = (0.1)/(0.082 xx 300)`
`= 4 xx 10^(-3)`
