1)

For the reaction ,

   $SO_{2}(g)+\frac{1}{2}O_{2}\rightleftarrows SO_{3}(g)$

  If KP= KC (RT)x

 Where, the symbols have usual  meaning , then the value of x is (assuming ideality)


A) -1

B) $-\frac{1}{2}$

C) $\frac{1}{2}$

D) 1

Answer:

Option B

Explanation:

For the given reaction, 

$\triangle n_{g}=n_{p}-n_{R}$ where nP = number  of moles of products

 nR= number of moles of reactants

  $K_{P}=K_{C}(RT)^{\triangle n_{g}}$

  $\triangle n_{g}=-(1/2)$
