Explain standard enthalpy of formation (Delta_(f)H^(@)). |
|
Answer» Solution :It is defined as the change in enthalpy accompanying the formation of one MOLE of a compound in its STANDARD state from the ELEMENTS in their standard states. Example : `H_(2(G)) + (1)/(2)O_(2(g)) rarr H_(2)O_((l)) , Delta_(f)H^(@) = -285.8 kJ mol^(-)1`. |
