`S(s)+O_(2)hArrSO_(@)(g)" "K_(1)=10^(52)`
`2S(s)+3O_(2)hArr2SO_(3)(g)" "K_(2)=10^(129)`
Calculate `K_("equilibrium")` for

A

`10^(77)`

B

`10^(154)`

C

`10^(25)`

D

`10^(181)`

Text Solution

Verified by Experts

The correct Answer is:
C
`K_(eq) = [SO_(3)]^(2)/([SO_(2)]^(2)[O_(2)])`
`K_(1) = [SO_(2)]/[O_(2)] = 10^(52)`
`K_(2) = [SO_(3)]^(2)/[O_(2)]^(3) = 10^(129)`
`K_(1)^(2) = [SO_(2)]^(2)/[O_(2)]^(2) = 10^(104)`
`K_(eq) = K_(2)/(K_(1))^(2) = 10^(129)/10^(104) = 10^(25)`
