K(p) for the following reaction at 700 K...

`K_(p)` for the following reaction at 700 K is `1.3xx10^(-3) atm^(-1)` . The `K_(c)` at same temperature for the reaction `2SO_(2) + O_(2) rarr 2SO_(3)` will be

A

`1.1xx10^(-2)`

B

`3.1xx10^(-2)`

C

`5.2xx10^(-2)`

D

`7.4xx10^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
D
`K_(p) = K_(c)(RT)^(Delta n)` R = Gas contant
`K_(c) = (K_(p))/((RT)^(Delta n)) = (1.3xx10^(-3))/((0.0821xx700)^(-1)) = 7.4xx10^(-2)`
