Why does Hess's law allow you to determine the enthalpy change of a reaction?
Hess's law states that the total enthalpy change for a chemical reaction is the sum of the enthalpy changes for each individual step of the reaction, regardless of the pathway taken. This allows us to determine the enthalpy change of a reaction by adding the enthalpy changes of multiple known reactions that, when combined, yield the desired overall reaction. By using this principle, we can calculate enthalpy changes even when the reaction cannot be measured directly. Thus, Hess's law provides a systematic way to obtain enthalpy values from existing data.

How can an unknown deltaH reaction be determined using Hess's law?
By manipulating known reactions with known enthalpy changes to create a series of intermediate reactions that eventually add up to the desired reaction whose enthalpy change is unknown. By applying Hess's law, the sum of the enthalpy changes for the intermediate reactions will equal the enthalpy change of the desired reaction, allowing you to determine its enthalpy change.
What is the enthalpy change for the reverse reaction?
The enthalpy change for the reverse reaction is equal in magnitude but opposite in sign to the enthalpy change for the forward reaction.
How is Hess's law used to measure enthalpy of a desired reaction?
... Intermediate equations with known enthalpies are added together.
How can one determine the change in enthalpy of a reaction?
The change in enthalpy of a reaction can be determined by measuring the heat released or absorbed during the reaction. This is typically done using a calorimeter, which allows for the precise measurement of the temperature change that occurs. The change in enthalpy is then calculated using the heat capacity of the system and the temperature change.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
How can one determine the enthalpy change in a chemical reaction using the concept of delta H in chemistry?
To determine the enthalpy change in a chemical reaction using the concept of delta H in chemistry, one can measure the heat released or absorbed during the reaction. This can be done using calorimetry, where the temperature change of the reaction mixture is monitored. The enthalpy change, represented by delta H, is calculated using the heat exchanged and the amount of reactants consumed or products formed in the reaction.
