WebGibbs free energy specifically refers to the energy associated with a chemical reaction that is available after accounting for entropy. In other words, Gibbs free energy is usable energy or energy that is available to do work. Spontaneous Reaction Less than 0 because energy is left over. Not Spontaneous or Spontaneous Backwards More than 0 http://www.chemistry.uoguelph.ca/educmat/chm1050/endweek04beginweek05F11.pdf
