1.	Calculate `DeltaH^(@)` for the reaction between ethene and water to form ethyl alcohol from the following data: `Delta_(c)H^(@)C_(2)H_(5)OH_((1))=-136kJ` `Delta_(c)H^(@)C_(2)H_(4(g))=-1410kJ` Does the calculated `DeltaH^(@)` represent the enthalpy of formation of liquid ethanol ?
Answer» `CH_(2)=CH_(2(g))+H_(2)O_((g))hArrCH_(3)CH_(2)OH_((g))` `DeltaH=sumnH^(@)f_("products")-sumnH^(@)f_("reactants")` `=(1xx-1368)-[(1xx(-1410)+(1xx-286))` `=-1368-[-1410-286]` `=-168-[-1696]` `DeltaH=328J//mol` No calculated value does not represent the enthalpy of formation of liquid enthanol. Standard enthalpy of formation for liquid ethanol is `-277.6kJ//mol.`
