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

A

`K_(p)=([ZnO] [CO_2])/([ZnCO_3])`

B

`K_(p)=(p_(ZnO)xx p_(CO_2))/(p_(ZnCO_3))`

C

`K_(p)=p_(ZnO)^2 xx p_(CO_2)`

D

`K_p=p_(CO_2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`ZnCO_(3)(s) Leftrightarrow ZnO_(s)+CO_(2(g))`
For solids, concentration or partial pressure is taken as unity
`K_(p)=p_(CO_2)`
