How many physical chemists does it take to wash a beaker? None. That's what organic chemists are for!

Re: Structure naming
I believe that it actually does! The book numbers the substituents from the second carbon onwards, in order to give each substituent the lowest number possible.

Re: Unique Reaction Rate
For a unique reaction rate, you must take into account the coefficient when calculating the rate -- for a normal reaction rate, one calculates the average rate and does not need to take the coefficients into account.

Three Laws of Thermodynamics (paraphrased):
First Law: You can't get anything without working for it.
Second Law: The most you can accomplish by work is to break even.
Third Law: You can't break even.

Re: WHat is the unit of k
K, the equilibrium constant, does not have a unit -- it is just a number.

Re: Post All Chemistry Jokes Here
In a sports relay race, a chemical kinetics specialist runs slowly, and his group loses the race. When the chemical kinetics specialist is asked why he ran slowly, his reply was “I always wanted to be the significant rate determining step”.

Re: Acidic vs. Basic Solution
You need to know whether or not the redox reaction is occurring in an acidic or basic solution because that determines whether or not you add hydroxide ions to either side in order to to get rid of the hydrogen protons (which combine with the hydroxide ions to make water).

Re: Orientations for Degeneracy
No, it's something that you're meant to calculate using the equations derived in class. I believe that the instances where we looked at molecules and noted the degeneracy were just examples of what it was.

Re: Can entropy be measured?
Yes, entropy can be measured. One way of measuring it is the following equation:
dS=q/T, where where dS represent change in entropy, q represents heat transfer, and T represents temperature. Since dS is the derivative, the integral of the equation can be used to calculate entropy.
