Find out the value of `K_(c)` for each of the following equilibrium from the value of `K_(p)`:
(`a`) `2NOCl_((g))hArr2NO_((g))+Cl_(2(g))`,
(`K_(p)=1.8xx10^(-2)atm` at `500 K`)
(`b`) `CaCO_(3(s))hArrCaO_((s))+CO_(2(g))`,
(`K_(p)=167 atm` at `1073 K`)

Explanation

(`a`) `Deltan=1`, `T=500K`,
`K_(p)=K_(c)(RT)^(Deltan)`
`:. K_(c)=(K_(p))/((RT)^(Deltan))`, (`R=0.0821 litre atm K^(-1)mol^(-1)`)
`K_(c)=(1.8xx10^(-2))/([(0.0821)(500)]^(1))`
`=4.38xx10^(-4)`
(`b`) `K_(c)=(167)/([(0.0821)(1073)]^(1))=1.90`
[`:' Deltan=1`, `T=1073 K`)
