The First Law of Thermodynamics
... Enthalpy of Formation Hess' Law can be formalized by defining Enthaply of Formation, which is the enthalpy change (DHf0) that occurs when one mole of a substance is formed from its elements in their standard state at 25oC. The Standard state of an element is its most stable form at 25oC. For example ...

General Concepts of Chemical Equilibrium
... In the reaction A+B DC+D If 0.2 mol of A is mixed with 0.5 mol of B in 1.0 L, find the equilibrium concentrations of A, B, C, and D. The equilibrium constant of the reaction is 4.0x108. It is clear that we have a high equilibrium constant which suggests that very little reactants may have been left ...
