Hess's Law Worksheet Answers. Calculate the enthalpy for the following reaction: Web hess's law states that since reactions 1 and 3 add to give reaction 2, we can also add the enthalpy of reaction 1 (oh) and the enthalpy of reaction 3 (hz) and get the enthalpy of.
The enthalpy change for a reaction is independent of. Web in short, the hess’s law is based on the fact that enthalpy is a state function, and therefore, δh rxn is the same whether the reaction takes place in one step or in a series of steps. Solution the measured enthalpy changes must be manipulated so that n2 is cancelled out, because it is not required in the.
