Steric Strain and Torsional Strain

Does torsional strain only exist between atoms separated by three bonds? And does steric strain only exist between atoms separated by four or more bonds?

Arranging substituents while naming

Do the prefixes "di", "cyclo", "tert", etc matter when we're arranging substituents in alphabetical order?

Order of naming

On page 102 of the course reader, why isn't the structure 1,6-dichlorocyclohexene called 2,3-dichlorocyclohexene? (starting at the double bond and going the other way)

Diamond and graphite

In the course reader, it says diamond is kinetically stable with respect to graphite. What does this mean?

Book problem 14.55

In the solutions manual for this problem, Nickel (reduction potential- -0.23V) is chosen as the cathode and water is chosen as the anode (reduction potential- +1.23V). Shouldn't the more negative reduction potential be used as the anode because it's more likely to be oxidized?

When the standard free energy change of a reaction is 0, why doesn't it mean that the system is at equilibrium?

Reversible processes

On page 9 of the course reader, after the derivation of energy used as a work of expansion, it says "Since the system is at equilibrium, it is a reversible process." Does that mean all systems at equilibrium involve reversible processes? Why?
