`CuSO_(4).5H_(2)O(s)hArrCuSO_(4).3H_(2)O(s)+2H_(2)O(s) K_(P)=0.4xx10^(-3) atm^(2)`
Which of following sttement are correct:
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 presence of aqueous tension of `24` torr, `CuSO_(4).5H_(2)O` can not loss molisture.
D. In presence of dry atmosphere in open container `CuSO_(4).5H_(2)O` will completely convert into `CuSO_(4).3H_(2)O`
