triple bonds vs double bonds

If a hydrocarbon has a double-bond and a triple-bond at both ends would we want to give the triple bond the lowest numbering or the double bond?

Self test 1.11A question b

The answer says that the name of the cycloalkene is 1,6-Dimethylcyclohexa-1,4-diene. I don't understand why they numbered their carbons in the counter-clockwise direction. Wouldn't counting clockwise be favored because of the functional groups attached to the ring?

Re: Quiz 2 Winter 2017

For number 5 wouldn't a lower activation energy make the rate of reaction more sensitive to an increase in temperature? because not as much thermal energy is needed to get the reaction going? Can someone clarify? thanks

fractional reaction order [ENDORSED]

Page 621 in the book gives an example in which a reaction has a fractional order; they don't really go into too much detail about why, can anyone explain?

Ch 14 Q #35

The solutions manual used the formula and said that at 25 degrees Celsius
My question is how they arrive at that equation?

Enthalpy of Sublimation

According to the book, enthalpy of sublimation must be equal to the sum of the enthalpies of fusion and vaporization? However, the book also says that it is equal to the enthalpy of the vapor minus the enthalpy of the solid. Can someone explain this?
