For the reaction : SO(2)(g)+(1)/(2)O(...

For the reaction :
`SO_(2)(g)+(1)/(2)O_(2)(g)hArr SO_(3)(g)`
If `K_(p)=K_(c ) (RT)^(x)` where the symbols have usual meaning, then the value of x is : (assuming ideality)

A

`-1`

B

`-(1)/(2)`

C

`(1)/(2)`

D

1

Text Solution

Verified by Experts

The correct Answer is:
B
`SO_(2)(g)+(1)/(2)O_(2)(g)hArr SO_(3)(g)`
`Delta n_(g)=1-(1+(1)/(2))=-(1)/(2)`
`therefore K_(p)=K_(c )(RT)^(-1//2)`
`therefore x = -1//2`
