Standard enthalpy of formation

Question

Why the eq. H2(g)+1/2 O2(g)-->H2O(g) doesn't represent standard enthalpy of formation of water?

Aman Bansal · Accepted Answer

Dear Neha,By Defination,The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 degrees Celsius). Its symbol is &Delta;HfO or &Delta;fHO.Best Of Luck...!!!!Cracking IIT just got more exciting,It&rsquo;s not just all about getting assistance from IITians, alongside Target Achievement and Rewards play an important role.ASKIITIANS has it all for you, wherein you get assistance only from IITians for your preparation and winby answering queries in the discussion forums.Reward points 5 + 15 for all those who upload their pic and download the ASKIITIANS Toolbar, just a simpleto download the toolbar&hellip;.So start the brain storming&hellip;. become a leader with Elite Expert League ASKIITIANSThanksAman BansalAskiitian Expert
