Chapter 14 First Law of Thermodynamics: energy cannot be created or destroyed - Chemical Reaction: system (the reaction itself) & surroundings (beaker, solvent, etc.) Spontaneous Processes: a process that DOES occur under a speciﬁc set of conditions without ongoing outside intervention. - ex: combustion of methane Nonspontaneous Process: a process that does NOT occur under a speciﬁc set of conditions Entropy: Qualitative - Entropy (S): a measure of how dispersed the system’s energy is. By removing the barrier the energy that was contained becomes dispersed throughout the container [Figure 14.1]
