WebThe standard enthalpy of formation of N H 3 is − 4 6. 0 kJ m o l − 1. If the enthalpy of formation of H 2 from its atoms is − 4 3 6 kJ m o l − 1 and that of N 2 is − 7 1 2 kJ m o l − 1, the average bond enthalpy of N-H bond in N H 3 is: WebThe definition of standard enthalpy of formation is the change in enthalpy when one mole of a substance is formed in its standard state from its constituent elements in their standard state at 298k and 1 atm. Since elements like Oxygen are in their standard state, there is no standard enthalpy of formation to talk about here.
