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

For the reaction, `SO_(2)(g) + (1)/(2)O_(2)(g)hArrSO_(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//2`

B

`-1`

C

`1//2`

D

`1`

Text Solution

Verified by Experts

The correct Answer is:
A

In general,
`K_(p)=K_(c)(RT)^(Delta n_(g))`
where `Delta_(ng)=(n_(p))_(g)-(n_(R))_(g)`
For the reaction
`SO_(2)(g)+(1)/(2)O_(2)(g)hArrSO_(3)(g)`
`Delta_(ng)=1 - (1+(1)/(2))= -(1)/(2)`
`:. K_(p)=K_(c)(RT)^(-1//2)`
