Ch.12: Thermodynamics Wednesday, January 20, 2016 9:56 AM • Why chemical reactions happen (and physical processes) • Demo: • Spontaneity: A spontaneous process that occurs without ongoing outside intervention ○ Ex. Ball rolling downhill ○ Ex. Water freezing at -10 degrees Celsius ○ Ex. Iron rusting • Reverse of spontaneous process: Nonspontaneous ○ Does not happen on its own ○ not necessarily impossible • Spontaneous reaction ○ May need help getting started ○ Not necessarily fast • What makes a reaction spontaneous ○ Is a spontaneous reaction equal to and exothermic reaction  Combustion reaction = yes  Demo reaction = no (spontaneous, but endot
