`CuSO_(4).5H_(2)O(s)CuSO_(4).3H_(2)O(s)+2H_(2)O(s) K_(p)=0.4xx10^(-3)atm^(2)` Which of following statement are correc:A. `DeltaG^(@)=-RTlnP_(H_(2)O)` where `P_(H_(2)O)="partial pressure of" H_(2)O` at equilibrium.B. At vapour pressure of `H_(2)O=15.2` torr relative humidity of `CuSO_(4).5H_(2)O "is"100%`C. In pressure of aqueous tension of `24` torr, `CuSO_(4).5H_(2)O` can not loss moisture.D. In presence of dry atmosphere in open container `CuSO_(4).5H_(2)O` will completely convert into `CuSO_(4).3H_(2)O` |
Answer» Correct Answer - B::C::D (A) `K_(p)=(P_(H_(2)O))^(2)` `=0.4xx10^(-3)=4xx10^(-4)atm^(2)` `(P_(H_(2^O)))_(equi)=2xx10^(-2)atm` `=2xx10^(-2)atm` `=2xx10^(-2)xx760=15.2` torr (B) Relative humidity`=(15.2)/(15.2)xx100=100%`(IfV.P.`=15.2` torr) (C) When `P_(H_(2)O)gt(P_(H_(2)O))_(equi)` backward shift so at `24` torr pressure reaction shift backward. (D) In dry atmosphere and open container reaction shift completely in forward. |
