Wouldn't this type of reaction violate the 2nd law of thermodynamics?[edit]

Because if the products have more energy than before, then their entropy has decreased. And since heat is drawn in from the surroundings, its entropy is decreased. So, the entropy of the entire system decreases, right? Or am I missing something?

The chemical potential energy is increased, and the heat energy is decreased, by the same amount, so no violation. StuRat 01:51, 12 February 2006 (UTC)[reply]

Please do not merge these separate 6 pages[edit]

The merge debate goes back to '05 (see: Talk:Endergonic). The result of the debate was to not merge. Moreover, it is standard protocol, e.g. according to both The Essential Dictionary of Science (Clark 2004) and the A to Z Dictionary of Thermodynamics (Perrot 1998), to have separate entries for such closely-related but subtly-different topics such as:

  • Exothermic – a process or reaction that involves the release of energy; usually in the form of heat.
  • Exothermic reaction – a chemical reaction in which heat is give out.

As well as for the other terms: endothermic, endothermic reaction, etc. For example, the melting of an ice-cube is an endothermic process; combustion evolves an exothermic reaction, warm-blooded animals are endothermic, arguing with other Wikipedians is an endergonic activity, etc. Help us expand on these separate stubs, but please don't merge. Wikipedia has unlimited storage space. Articles are sure to grow. Thanks:--Sadi Carnot 17:30, 22 March 2006 (UTC)[reply]
