For `CaCO_(3)(s) hArr CaO(s)+CO_(2)(g), K_(c)` is equal to …………..

A

`K_(c)=(1)/([CO_(2)])`

B

`K_(c)=[CO_(2)]`

C

`K_(c)=([CaO][CO_(2)])/([CaCO_(3)])`

D

`K_(c)=([CaCO_(3)])/([CaO][CO_(2)])`

Text Solution

Verified by Experts

The correct Answer is:
B
`CaCO_(3)(s) hArr CaO(s)+CO_(2)(g)`
According the to of law ,ass action,
`K_(c )=[CO_(2)]`, because the concentration of solid substance is taken as unity.
