Question

Explain Hess's law of constant heat summation ?​

Answer 1

Heyaa !!!
☺☺☺

▶Hess's Law of Constant Heat Summation (or just Hess's Law) states that regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes.
➡This law is a manifestation that enthalpy is a state function.
▶Hess's law states that energy changes are state functions.
➡The amount of energy depends only on the states of the reactants and the state of the products, but not on the intermediate steps.
➡Energy (enthalpy) changes in chemical reactions are the same, regardless whether the reactions occur in one or several steps.

Thanks
and i hope you can get it.

$see \: here \: for \: answer$

$hess \: law \:$

If a reaction takes place in several steps then it's standard reaction enthalpy is the sum of the standard enthalpies of the intermediate reaction into which the overall reaction may be divided at the same temperature .
