Would torsional strain be negative if you were moving from a less stable conformation to a more stable one?

Do halides have priority over double bonds? I'm referring specifically to 1,6-dichloro-cyclohexane on page 105 of the course reader.

Do halides always come first in the name or does it go alphabetically? (I.e. If there was an ethyl and a fluorine anion attached to the same carbon, which would be listed first?)

I know you give preference to double bonds and functional groups when numbering, but which is more important? If you had a choice between setting a functional group at the second carbon or a double bond starting at the second carbon, which would you choose?

On page 163 of the Intro to Organic Chemistry textbook, it says "When \Delta G^o r <0, the exergonic reaction is favorable and K>1. When \Delta G^o r >0, the endergonic reaction is unfavorable and K<1." I believe there's an error here, but I just wanted to make sure. Im also unsure about w...

In example 2 on course reader page 85, it is stated that a nucleophile (denoted :Nu) donates electrons to and bonds with the central carbon atom. The Cl connected to the carbon is also electron rich because of its higher electronegativity. Is it considered a nucleoniphile as well or do nucleophiles ...

On page 69 of the course reader, it says $k[A]^N[B]{_{0}}^{M}[C]{_{0}}^{L}=k'[A]^{N}$ . Why is A not an initial concentration?

I'm confused as to where the $-\frac{1}{a}$ goes when you integrate the 2nd order differential rate law, $-\frac{1}{a}*\frac{d[A]}{dt}=k[A]^{2}$ , to get $-\frac{d[A]}{[A]^2}=kdt$ . Are we assuming a equals 1? If so, why?

It is stated that potential is maximized when the process is reversible and there's very little current, but what is the explanation behind this?

What is the difference between E0redox and E0cell? On page 50 of the course reader, when we are given two half reactions, we want to reverse the sign of the iron half reaction to get a positive cell potential. In the gold example on page 52, E0redox is allowed to be negative. Why is this?

What exactly is a microstate? Is it a location, an energy level, or something else?

If enthalpy is the amount of heat released and absorbed at a constant pressure, why does the course reader and textbook alternate between using q and $\Delta h$ ? Is $\Delta h$ used when pressure isn't constant?

What did Prof. Lavelle mean when he said "the most efficient work is done along an equilibrium pathway"?
