How to draw and label an enthalpy diagram?
Enthalpy diagrams are an easy way to see how the energy changes in a reaction over time. We draw them by knowing the delta H of the reaction and the activation energy. If delta H is positive then it's an endothermic reaction and the product energy is higher than the starting energy.
How is enthalpy related to the first law of thermodynamics?
Because the reaction is run at constant pressure, the change in the enthalpy that occurs during the reaction is equal to the change in the internal energy of the system plus the product of the constant pressure times the change in the volume of the system. Substituting the first law of thermodynamics into this equation gives the following result.
Which is an example of an enthalpy reaction?
An example of this is when we dissolve ammonium chloride in water. If you do this in a test tube you can actually feel the test tube getting colder, because it needed to take in heat (energy) for the reaction to occur. The actual delta H for this reaction is 18 kJ/mol.
What is the relationship between enthalpy and internal energy?
We will therefore abbreviate the relationship between the enthalpy of the system and the internal energy of the system as follows. The change in the enthalpy of the system during a chemical reaction is equal to the change in its internal energy plus the change in the product of the pressure times the volume of the system.
