ΔH (Change in Enthalpy)

Definition

ΔH represents the change in enthalpy during a chemical reaction. It's essentially the total energy change that occurs when reactants transform into products.

Enthalpy (H): This is a measure of total energy in a thermodynamic system. It includes both internal energy and work done by pressure-volume work.

Entropy (S): This measures disorder or randomness within a system. In many natural processes, entropy tends to increase over time.

Gibbs Free Energy (∆G): This value predicts whether a reaction will occur spontaneously at constant temperature and pressure.
