The equilibrium constant for the reaction:
`SO_3(g) hArr SO_2(g) +1/2O_2(g)` is 0.18 at 900 K.
What will be the equilibrium constant for the reaction:
`2SO_2(g) + O_2(g) hArr SO_3(g)`

Explanation

To find the equilibrium constant for the reaction:

\[ 2SO_2(g) + O_2(g) \rightleftharpoons SO_3(g) \]

given that the equilibrium constant for the reaction:

\[ SO_3(g) \rightleftharpoons SO_2(g) + \frac{1}{2}O_2(g) \]
