Document Summary
There is a subreddit for the course as well as a facebook page: /r/biol201/ The quality of energy depends on how much of the energy is free, or not used up as heat and disorder: enthalpy/total energy: h, free energy: g. G = h t s: g = final g initial g, g < 0: S is entropy, the measure of disorder in a system. The change of free energy determines whether a reaction will react spontaneously or not. There is a net release of free energy. Reaction is thermodynamically favourable and will occur spontaneously under the right conditions: g > 0: There is a net gain of free energy. Reaction is not thermodynamically favourable and will not occur spontaneously under normal conditions: g = 0: The standard free energy change in a system is denoted g0": g0": free energy change at normal conditions:
