Select the correct statements for the equilibrium under standard conditions. `H_(2)O(s) hArr H_(2)O(l),DeltaS_(1)^(Theta)` `H_(2)O(l) hArr H_(2)O(v), Delta_(2)^(Theta)` `H_(2)O(s) hArr H_(2)O(v), DeltaS_(3)^(Theta)`A. `DeltaS_(1)^(Theta) gt DeltaS_(2)^(Theta)`B. `DeltaS_(2)^(Theta) gt gt gt DeltaS_(1)^(Theta)`C. `DeltaS_(3)^(Theta) gt DeltaS_(2)^(Theta)`D. `DeltaS_(3)^(Theta) gt DeltaS_(1)^(Theta)`

Answer» `H_(2)O(s)` has more ordered arrangement. Also, `DeltaS^(Theta)_(2)`
`= S_(H_(2)O)^(Theta)(l) - S_(H_(2)O)^(Theta)(l)`
`DeltaS_(1)^(Theta) = S_(H_(2)O)^(Theta)(l) -S_(H_(2)O)^(Theta)(s)`
`:. S_(H_(2)O(v))^(Theta)` is maximum and thus `DeltaS_(2)^(Theta) gt gt gt DeltaS_(1)^(Theta)`.
