Question

explain the Hess's Law Of Constant heat summation​

Answer 1

Answer:

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 Of Constant heat summation✪

★The heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step for several steps.

★The chemical equation can be treated as ordinary algebraic expressions and can be added or subtracted is called the required equation. thethe corresponding enthalpies of reactions are also manipulated in the same way so as to give the enthalpy of reaction for the desired chemical equation.

★Utility of Hess's law is considerable in almost all the thermo chemical numericals Hess's law is used.

★One of the important applications of has lower is to determine enthalpy of reaction which is difficult to determine experimentally.
