Consider the pertial decomposition of `A` as
`2A(g)hArr2B(g)+C(g)` At equilibrium `700`mL gaseous mixture contains `100`mL of gas C at `10` atm and `300K` what is the value of `K_(p)` for the reaction ?

A

`(40)/(7)`

B

`(1)/(28)`

C

`(10)/(28)`

D

`(28)/(10)`

Text Solution

Verified by Experts

The correct Answer is:
C
`underset(v=600)underset(v-2v'+2v'+v'=700)underset(v'=100)underset(v-2v')underset(v)(2A(g))hArrunderset(2v')(2B(g))+underset(v')(C(g))`
`underset(=(40)/(7))underset(10xx(400)/(700))underset(400)(2A(g))hArrunderset((20)/(7))underset(10xx(200)/(700))underset(200)(2B(g))+underset((10)/(7))underset(10xx(100)/(700))underset(100)(C(g))`
`K_(P)=(((20)/(7))^(2)xx(10)/(7))/(((40)/(7))^(2))=(20xx20xx10)/(40xx40xx7)=(10)/(28)`
