Homework Answers
Standard enthalpy of formation of a compound is defined as the enthalpy change during the formation of one mole of a compound in standard state from its constituent elements when they react with each other at STP in their standard States.
In case 2 the equation represents the standard enthalpy of formation of Xenon tetrafluoride but in the remaining options the equations do not represent the enthalpy of formation of products because to get those products constituent elements in their standard States are not reacted with each other.
