SO 2( g )+(1/2) O 2( g ) leftharpoons SO 3( g ) K p = K C ( RT ) x x =Δ n g = no. of gaseous moles in product - no. of gaseous moles in reactant =1-(1+(1/2))=1-(3/2)=(-1/2)

Q. For the reaction, $S O_{2} (g) + \frac{1}{2} O_{2} (g) ⇌ S O_{3} (g)$ if $K_{P} = K_{C} (RT)^{x}$ where, the symbols have usual meaning, then the value of $x$ is (assuming ideality)

$S O_{2} (g) + \frac{1}{2} O_{2} (g) ⇌ S O_{3} (g)$
$K_{p} = K_{C} (RT)^{x}$
$x = Δ n_{g} =$ no. of gaseous moles in product
- no. of gaseous moles in reactant
$= 1 - (1 + \frac{1}{2}) = 1 - \frac{3}{2} = \frac{- 1}{2}$

Q. For the reaction, SO2​(g)+21​O2​(g)⇌SO3​(g) if KP​=KC​(RT)x where, the symbols have usual meaning, then the value of x is (assuming ideality)

SO2​(g)+21​O2​(g)⇌SO3​(g) Kp​=KC​(RT)x x=Δng​= no. of gaseous moles in product - no. of gaseous moles in reactant =1−(1+21​)=1−23​=2−1​

Q. For the reaction, $S O_{2} (g) + \frac{1}{2} O_{2} (g) ⇌ S O_{3} (g)$ if $K_{P} = K_{C} (RT)^{x}$ where, the symbols have usual meaning, then the value of $x$ is (assuming ideality)

- $\frac{1}{2}$

$\frac{1}{2}$

$S O_{2} (g) + \frac{1}{2} O_{2} (g) ⇌ S O_{3} (g)$
$K_{p} = K_{C} (RT)^{x}$
$x = Δ n_{g} =$ no. of gaseous moles in product
- no. of gaseous moles in reactant
$= 1 - (1 + \frac{1}{2}) = 1 - \frac{3}{2} = \frac{- 1}{2}$
