WebbEntropy is a measure of disorder. Statistical thermodynamics defines the entropy of a system in the following way: S = k l n ( W) S = k\ ln (W) S = k ln(W) where: k - Boltzman's constant, W - the number of ways in which the macroscopic thermodynamic state of the system can be realized through microscopic states.

The standard enthalpy of formation equals enthalpy change. For several substances, we’ve determined this out. The reactants go through several chemical changes and get combined to generate different products in each particular chemical reaction. The change in enthalpy is represented as ΔrH for any such reaction.
