In chemistry, the standard molar entropy is the entropy content of one mole of substance, under conditions of standard temperature and pressure. By comparing the entropies S and enthalpies H of products and reactants in a chemical reaction, we can determine whether the reaction will go forward or backwards. If the Gibbs free energy (G = H  TS) is negative, the forward reaction will take place. The standard molar entropy is usually given the symbol S^{0}, and the units J/(mol·K) (joules per molekelvin). Chemistry (in Greek: Ï‡Î·Î¼ÎµÎ¯Î±) is the science of matter that deals with the composition, structure, and properties of substances and with the transformations that they undergo. ...
