N(2(g)) + 3H(2(g)) harr 2NH(3(g)) is a g...

`N_(2(g)) + 3H_(2(g)) harr 2NH_(3(g))` is a gaseous phase equilibrium reaction taking place at 400K in a 5 L flask. For this

A

`K_(c)=K_(x)`

B

`K_(c)=25K_(x)`

C

`K_(x)=25K_(c)`

D

`K_(c)=5K_(x)`

Text Solution

Verified by Experts

The correct Answer is:
B
`K_(P)=K_(X)(P)^(Delta n_((g)))`
`K_(c)(RT)^(Delta n_((g)))=K_(X)(P)^(Delta n_((g)))`
`K_(c)=K_(X)((P)/(RT))^(Delta n_((g)))`, PV=RT
`((P)/(RT))=(1)/(V)=(1)/(5), Delta n_((g))= -2`
`K_(c)=K_(X)((1)/(5))^(-2), K_(c)=25K_(X)`
