When heated , ammonium carbamate decomate decompoes as follows :
NH_(4)COOH_(2)(s) hArr2NH_(3)(g)+CO_(2)(g)`
`At a certain temperature , the equilibrium pressure of the system is 0.318atm `K_(p) ` for the reaction is:

Options

A. `0.128`
B. `0.426`
C. `4.76xx10^(-3)`
D. `2.24 xx 10^(-2)`

Answer

C

Explanation

`{:(NH_(4)COONH_(2) (s) ,hArr, 2NH_(3)(g) ,+,CO_(2)(g)),("Eq. pressure",,"-2p",,"p"):}`
`3P=0.318 rArr P= 0.106`
`P_(NH_(3)) =2 xx 0.106 =0.212`
`P_(CO_(3)) =0.106`
`K_(p) = P_(Nh_(3))^(2). P_(CO_(2))= 0.212 xx 0.212 xx0.106`
