1.	Two similar reactions are given below : H_(2)(g) + (1)/(2)O_(2)(g) rarr H_(2)O(g), DeltaH = = DeltaH_(1) H_(2)(g)+(1)/(2) O_(2)(g) rarr H_(2)O(l), DeltaH= DeltaH_(2) In terms of magnitude of DeltaH,
Answer» `DeltaH_(1) gt DeltaH_(2)` `DeltaH_(1)lt DeltaH_(2)` `DeltaH_(1) = DeltaH _(2)` None of these is correct Solution :`DeltaH_(2) gt DeltaH_(1)` because when `H_(2)O(G)` consdenseto`H_(2)O(l)`, HEAT of CONDENSATION is evolved.Hence, `DeltaH_(1) ltDeltaH_(2)`.
