At 700K, the equilibrium constant K(p), ...

At 700K, the equilibrium constant `K_(p)`, for the reaction `2SO_(3(g))hArr2SO_(2(g))+O_(2(g))` is `1.8xx10^(-3)` atm. The value of `K_(c)` for the above reaction at the same temperature in moles per litre would be

A

`1.1xx10^(7)`

B

`6.2xx10^(-7)`

C

`3.1xx10^(-5)`

D

`9.3xx10^(-7)`

Text Solution

Verified by Experts

The correct Answer is:
C
`K_(p)=K_(c)(RT)^(Deltan),Deltan=3-2=1`
`1.8xx10^(-3)=K_(c)(0.0832xx700)^(1),`
`K_(c)=(1.8xx10^(-3))/(0.0832xx700)=3.09xx10^(-5)`
