In the two gaseous equilibria (i) and (...

In the two gaseous equilibria (i) and (ii) , at a certain temperature,
`(i) SO_(2)(g) +1//2 O_(2)(g) hArr SO_(3)(g) ....K_(1)`
`(ii) 2SO_(3)(g) hArr 2SO_(2)(g) +O_(2)(g) .....K_(2)`
If `K_(1) `is `4 xx 10^(-3)` then `K_(2)` will be

A

`8.0 xx 10^(-3)`

B

`16.0 xx 10^(-6)`

C

`6.25 xx 10^(4)`

D

`6.25 xx 10^(8)`

Text Solution

Verified by Experts

The correct Answer is:
C
For the given reactions `K_(2)=(1)/((K_(1))^(2))`
Thus `K_(2)=(1)/((4 xx 10^(-3))^(2))=6.25 xx 10^(4)`
