Process
... A process or transformation is a change in the state of the system over time, starting with a definite initial state and ending with a definite final state. The process is defined by a path, which is the continuous sequence of consecutive states through which the system passes, including the initial ...

Entropy and Free Energy
... has a fundamental molecular significance: It is a measure of the disorder of a system. This disorder can be asymmetry or displacement. This significance is relevant in the sub-atomic nature of the physical universe as well. Boltzmann proposed that entropy is related to the number of different micros ...

... It is the tendency of that molecular specie to chemically react, which depends on both its concentration and internal energy of the molecule. In a chemical reaction A ! B , the difference between A and B is amount of chemical energy available to do work per unit of molecule. At chemical equilibrium, ...
