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.

In an open system, energy can be exchanged through heat and work, and the same goes fo...
