what is Hess law application to it
Answers
Answer:
Applications of Hess's Law:
Thermochemical equations can be added subtracted or multiplied like ordinary algebraic equations. Hess's law is useful to calculate heats of many reactions which do not take place directly. It is useful to find out heats of extremely slow reaction.
Hess' law can be used to determine the overall energy required for a chemical reaction, when it can be divided into synthetic steps that are individually easier to characterize. This affords the compilation of standard enthalpies of formation, that may be used as a basis to design complex syntheses.
The Hess's law states that when reactants are converted to products, the change in enthalpy is the same whether the reaction takes place in one step or in a series of steps. Consider the reaction for the formation of carbon monoxide (CO) from graphite.
