`Ag^(+)+hArr|Ag(NH_(3))_(2)|^(+), k_(1) = 6.8 xx 10^(-3)` `[Ag(NH_(3))]^(+) + NH_(3)hArr |Ag(NH_(3))_(2)|, k_(2) = 1.6xx10^(-3)` Then the formation constant or `|Ag(NH_(3))_(2)|^(+)` isA. `1.08 xx 10^(-7)`B. `1.08 xx 10^(-5)`C. `1.08 xx 10^(-9)`D. none of these

Answer» Correct Answer - B
As the reaction takes place in two stages
`k = k_(1)xx k_(2) = (6.8 xx 10^(-3)) xx (1.6xx 10^(-3))`
= `10.8 xx 10^(-6) = 1.08xx 10^(-5)`
