Another way to state Hess' Law is The enthalpy change of an overall process is the sum of the enthalpy changes of its individual steps. The process needed to answer the question above is based on the principle that if you add two or more equations to get a new equation, you must add the ΔH's to get the ΔH for the new equation.

The enthalpy of a given chemical reaction is constant, regardless of the reaction happening in one step or many steps. Another way to state Hess' Law is: If a chemical equation can be written as the sum of several other chemical equations, the enthalpy change of the first chemical equation equals the sum of the enthalpy changes of the other ...

these reactions: C(s) + O2(g) → CO2(g) ΔHo = -393.5 kJ CO(g) + ½ O2(g) → CO2(g) ΔHo = -283.0 kJ According to Hess's Law, we can combine the above two reactions in a manner that will give the desired reaction. Note that if we reverse the second reaction and add it to the first reaction, we will obtain the

Hess's Law, also known as "Hess's Law of Constant Heat Summation," states that the total enthalpy of a chemical reaction is the sum of the enthalpy changes for the steps of the reaction.Therefore, you can find enthalpy change by breaking a reaction into component steps that have known enthalpy values. This example problem demonstrates strategies for how to use Hess's Law to find the enthalpy ...
