The value of `K_(p)` fot the reaction `2H_(2)O(g) + 2CI_(2)(g)hArr4HCI(g) + O_(2)(g)` is `0.03` and at `427^(@)C`, when the partial pressure are expressed in atmosphere then the value of `K_(c)` for the same reaction is:

Options

A. (A) `5.23``10^(-4)`
B. (B) `7.34xx10^(-4)`
C. (C) `3.2xx10^(-3)`
D. (D) `5.43xx10^(-4)`

Answer

A

Explanation

`2H_(2)O(g)+2CI_(2)(g)hArr2HCI(g)+O_(2)(g)`
`K_(p)=0.03 T=427^(@)C=700K`
`K_(p)=K_(c)(RT)^(1)`
`K_(c)=(K_(p))/(RT)=[(0.03]/(0.082xx700)]`
`K_(c)=5.23xx10^(-4)`
