WebbHess's law allows the enthalpy change (ΔH) for a reaction to be calculated even when it cannot be measured directly. This is accomplished by performing basic algebraic … WebbUse Hess’ Law which states the heat involved in a chemical process is the same whether it takes place in one step or multiple steps. First proposed by Henri Hess in 1840, this is sometimes referred to as the law of constant heat summation and is a consequence of the law of conservation of energy.
