Q.5) Define Heat of formation
​

Answer 1

Answer:

hope it's helped

Explanation:

.The standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements, with all substances in their standard states.

.What is heat of formation equation?

This equation essentially states that the standard enthalpy change of formation is equal to the sum of the standard enthalpies of formation of the products minus the sum of the standard enthalpies of formation of the reactants. and the standard enthalpy of formation values: ΔH fo[A] = 433 KJ/mol. ΔH fo[B] = -256 KJ/mol.

Answer 2

Answer:

Define-:

HEAT OF FORMATION :-The heat released or absorbed during the formation of a pore substance from its elements at constant pressure in their standard states.
