Special cases with nomenclature [ENDORSED]

Are there cases with nomenclature when even knowing the naming conventions isn't helpful and you'd have to already know the molecule in question in order to know its structure?

Three-step electrochemical reactions

Are there any notable instances of reactions requiring three half-reactions or half-steps (in nature, industry, or anywhere else)?

Termolecular reactions

Are there any notable or important/widely used reaction mechanisms which rely on an intermediate termolecular (or even perhaps interactions with higher amounts of molecules) reaction step, despite the relatively low likelihood of a termolecular reaction as opposed to a bimolecular or unimolecular one?

Example on page 50 in Course Reader

On page 50 of the course reader, the example of a gold ring being tested to dissolve in Nitric Acid is given. "Will a gold ring dissolve in 1M Nitric Acid (HNO_3) to form a 1M Au(3+) solution?" After finding the value of delta_G°(redox), how would you know that the gold does not dissolve i...

Gibbs Free Energy

Is the actual Gibbs energy - not the change in Gibbs energy - ever important? What exactly is the difference, and if it indeed a valuable metric, how is it used in chemistry in the real world (e.g. experiments, industry, etc.)?

Heat capacities of materials [ENDORSED]

What are some of the properties (e.g. molecular bond strength, size of molecule, etc.) of a material that factor into its heat capacity? Also, are there any circumstances under which a material will have a non-constant heat capacity (for example, temperature or pressure extremes) - and if so, what a...

Potential energy surfaces and experimental chemistry

How are potential energy surfaces modeled and used in real life? What information can we get out of them and what subset of mathematics would be required to analyze and understand high-dimension potential energy surfaces?
