Two solids dissociates as follows
`A(s) rarr B(g) + C(g), K_(P_(1)) = x atm^(2)`
`D(s) rarr C(g) + E(g), K_(P_(2)) = y atm^(2)`
The total pressure when both the solids dissociate simultaneously is :

A

`sqrt(x+y)atm`

B

`2(sqrt(x+y))atm`

C

`(x+y)atm`

D

`x^(2)+y^(2) atm`

Two solids A and D dissociates into gaseous products as follows A(s)hArrB(g)+C(g),K_(p_(2))=300 D(s)hArrE(g) + C (g) K_(P_(2)) = 600 at 27^(@)C , then find the total pressure of the solid mixture.

Solid A and B are taken in a closed container at a certain temperature. These two solids decompose and following equilibria are established simultaneously A(s)hArr X(g) + Y(g) K_(P_(1)) = 250 atm^(2) B(s)hArrY(g) + Z(g) K_(P_(2)) = ? If the total pressure developed over the solid mixture is 50 atm. Then the value of K_(P) for the 2^(nd) reaction.
