Answer» <P>`2.5xx10^(-3)` `K_(1)=([P_(2)][Q_(2)])/([PQ]^(2))=2.5xx10^(5)` `PQ+1//2R_(2)hArrPQR.` `K_(2)=([PQR])/([PQ][R_(2)]^(1//2))=5xx10^(-3)` Required equlibrium is: `1//2P_(2)+1//2Q_(2)+1//2R_(2)hArrPQR,` `K_(3)=([PQR])/([P_(2)]^(1//2)[Q_(2)]^(1//2)[R_(2)]^(1//2))` `K_(3)=K_(2)xxsqrt((1)/(K_(1)))` `=5xx10^(-3)xxsqrt((1)/(2.5xx10^(5)))=(5xx10^(-3))/(0.5xx10^(3))=1XX10^(-5)` |
