FAQs

Question: What is the difference between enthalpy and internal energy?
Answer: Enthalpy is a measure of total energy in a system, including internal energy and the energy required to make space for it by displacing its environment, while internal energy is the total energy contained within the system.

Question: How do I calculate the change in enthalpy for a reaction?
Answer: The change in enthalpy can be calculated using the formula ΔH = H(products) - H(reactants), where H represents the enthalpy of the respective substances.
