Joseph Chapter 19: Chemical Thermodynamics Spontaneous process – one that proceeds on its own without any outside assistance. Most reactions and chemical processes have an inherent directionality: They are spontaneous in one direction and nonspontaneous in the reverse direction. The spontaneity of a process is related to the thermodynamic path the system takes from the initial state to the final state. In a reversible process, both the system and its surroundings can be restored to their original state by exactly reversing the change. In an irreversible process the system cannnot retum to its original state without there being a permanent change in the surroundings. Any spontaneous process is irreversible. A process that occurs at a constant temperature is said to be isothermal. Entropy - The spontaneous nature of processes is related to a thermodynamic state function The unit is J/K Molecules can undergo three kinds of motion: In translational motion the en tire molecule moves in space. Molecules can also undergo vibrational motion, in which
