WebThe enthalpy change for the process (\(\Delta H\)) is independent of the route taken (This is Hess’s law). The enthalpy change ( \(\Delta H\) ) is proportional to the quantities of reactants and ... WebHess's law is a relationship in physical chemistry named after Germain Hess, a Swiss-born Russian chemist and physician. This law states that if a reaction takes place in several steps, then the standard reaction enthalpy for the overall reaction is equal to the sum of the standard enthalpies of the intermediate reaction steps, assuming each ...
