For reacrtion 2NOC1(g) hArr 2NO(g) + C1(...

For reacrtion `2NOC1(g) hArr 2NO(g) + C1_(2)(g)` , `K_(c)` at `427^(@)C` is `3xx10^(-6)` L `mol^(-1)`. The value of `K_(p)` is nearly

A

`7.50xx10^(-5)`

B

`2.50xx10^(-5)`

C

`2.50xx10^(-4)`

D

`1.75xx10^(-4)`

Text Solution

Verified by Experts

The correct Answer is:
D
`2NOC1_((g))hArr2NO_((g)) + C1_(2(g))`
`K_(p) = K_(C)(RT)^(Delta n)`
`K_(p) 3xx10^(-6)(0.0821xx700)`
`=172.41xx10^(-6) = 1.72xx10^(-4)`
