The equilibrium constant for the given reaction:
`SO_(3(g))hArrSO_(2(g))+1//2O_(2(g))`, `(K_(c)=4.9xx10^(-2))`
The value of `K_(c)` for the reaction:
`2SO_(2(g))+O_(2(g))hArr2SO_(3(g))`, will be :

Options

A. 416
B. `2.4 xx 10^(-3)`
C. `9.8 xx 10^(-2)`
D. `4.9 xx 10^(-2)`

Answer

A

Explanation

`K_(c) =(1)/((K_(c))^(2)) = (1)/((4.9 xx 10^(-2))^(2)) =416.7`
