For the reaction, `ZnCO_(3)(s) hArr ZnO(s)+CO_(2)(g)` expression for the partial pressure constant for the above reaction would be

Options

A. `K_(p)=([ZnO][CO_(2)])/([ZnCO_(3)])`
B. `K_(p)=(p_((ZnO))xxp_(CO_(2)))/(p_(ZnCO_(3)))`
C. `K_(p)=p_((ZnO))^(2)xxp_(CO_(2))`
D. `K_(p)=p_(CO_(2))`

Answer

D

Explanation

For reaction, `ZnCO_(3)(s) hArr ZnO(s)+CO_(2)(g)`
`K_(p)=(p_((ZnO))xxp_(CO_(2)))/(p_((ZnCO_(3))))`
Now, `p_((ZnCO_(3)))=p_((ZnO))=1` as per conventions
`:. K_(p)=p_(CO_(2))`
