Re: Post All Chemistry Jokes Here

Organic chemistry is difficult, it causes alkynes of trouble.

Re: Post All Chemistry Jokes Here

I'd post a chemistry joke, but I know I wouldn't get a reaction

Re: Branched vs. Unbranched

I don't think it will matter whether or not the structure you draw is branched or unbranched, but just remember that each one will have a different name

Re: Slow Step

If two steps are given in a mechanism, we will also be told whether each step is slow or fast.

Re: k'

As far as my understanding, yes, it is simply the rate constant for a reverse reaction. It can be used to evaluate K or k in the equation K=k/k' (looking at the relationship between equilibrium constant and rate constant).

Re: -k value and Half Life

A negative k value can be found in zeroeth and first order reactions.

Re: Entropy

the more complex molecule will have the higher entropy, in order to figure out which one is more complex you can look at the shape of the molecule and at the individual elements that make it up

Statistical Entropy vs. Thermodynamic Entropy

What is the difference between statistical entropy and thermodynamic entropy? I know that the 2 different equations used to calculate them can lead to the same result but could someone please elaborate on how they are conceptually different?
Thank you!

Re: Need some clarification on finding enthalpy for a reaction.

We do products minus reactants because whenever we are looking for the change in something, the equation is always final-initial
