Question

how does Hess's law follow 1st law of thermodynamics?

Anita Dahiya · Accepted Answer

Hess's law is an expression of first law of thermodynamics - law
of conversation of energy According to the first law of
thermodynamics energy of a system remains constant - neither
created nor destroyed Hess's law states that standard enthalpy of a
reaction is the sum of the intermediate enthalpies, and is
independent of the path taken for the reaction to proceed
Therefore, it is clear that Hess's law follows first law of
thermodynamics
