Which of the following equlibria would have highest and lowest value of `K_(p)` at a commone temperature?

A

`BeCO_(3) hArr BeO+CO_(2)`

B

`SrCO_(3) hArr SrO+CO_(2)`

C

`CaCO_(3) hArr CaO+CO_(2)`

D

`BaCO_(3) hArr BaO +CO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`K_(P)= P_(CO_(2))`
`P_(CO_(2)) (uarr) = K_(P) (uarr)`
Stability order:
`BeCO_(3) lt MgCO_(3) lt CaCO_(3) lt SrCO_(3) lt BaCO_(3)`
