Hess’s law, also called Hess law of constant heat summation, is one of the important outcomes of the first law of thermodynamics. The enthalpy change in a chemical or physical process is similar whether it is carried out in one step or in several steps. Hess's law of constant heat summation was derived … See more Let us discuss some practical areas where Hess’s law is applied. As an example, let us take the formation of Sulphur Trioxide gas from Sulphur, which is a multistep reaction involved in Sulphur Dioxide gas formation. Let us find … See more As we all know that enthalpy is a state function, and thereby, it is independent of the path taken to reach the final state from the initial state. Hess’s law says that for a multistep reaction, the standard reaction enthalpy is … See more S + 32O2 → SO3, where, △HR=−94.95KCal/mol Therefore, in simple words, we can state as follows. △HR= △H2+ △H1+ … See more WebHess's Law Hess's Law is based on the conservation of energy.
