For a reaction,
`SO_(2) (g) + 1//2O_(2)(g) to SO_(3)(g)` if `K_(p)=1.7 xx10^(12)` at `20^(@)C` and 1 atm pressure , then value of `K_(c)` is

A

`1.7xx10^(12)`

B

`0.7xx10^(12)`

C

`8.33xx10^(12)`

D

`1.2xx10^(12)`

Text Solution

Verified by Experts

The correct Answer is:
C
`K_(p)=K_(c)(RT)^(Deltan)`
or `K_(c)=(K_(p))/((RT)^(Deltan))=(1.7xx10^(12))/((0.082xx293)^(-1//2))`
`=1.7xx10^(12)xxsqrt(0.082xx293)`
`=1.7xx10^(12)xx4.9=8.33xx10^(12)`
