For the decomposition reaction:
`NH_(2)COONH_(4(s))hArr2NH_(3(g))+CO_(2(g))`.
`(K_(p)=2.9xx10^(-5)atm^(2))`
The total pressure of gases at equilibrium when `1 "mole"` of `NH_(2)COONH_(4(s))` was taken to start with would be:

A

`0.0194 atm`

B

`0.0388 atm`

C

`0.0582 atm`

D

`0.0766 atm`

Text Solution

Verified by Experts

`NH_(2)COONH_(4(s))hArrunderset(2P)(2NH_(2(g)))+underset(P)(CO_(2(g)))`
`K_(p)=2.9xx10^(-5)atm^(3)`
`K_(p)=(2P)^(2)xxP=2.9xx10^(-5)`
or `P=0.0194`
`:. Total pressure=2P+P=3P`
`=3xx0.0194=0.0582 atm`
