1.	The value of `DeltaH_(O-H)` is `109Kcal//mol` . The enthalpy of formation of 1 mole of water in gaseous state will beA. `109xx2KJmol^(-1)`B. `109KJmol^(-1)`C. data is not sufficient to predict itD. `109xx4Kcalmol^(-1)`
Answer» Correct Answer - B Formation of water does not merely require the formation of two `O-H` bonds but also require the dissociation of `1mol` of `H_(2)` and `(1)/(2)mol` of `O_(2)` `H_(2)(g)+(1)/(2)O_(2)(g)rarrH_(2)O(g)`
