Coefficients are only placed in the rate law when you are given the rate limiting step in a reaction mechanism. If don't have such information, you cannot assume that the overall reaction determines the rate law. To determine the rate law in that scenario, you must calculate it using different exper...

You can see that Cyclohexane only has one substituent. Since cyclohexane is a ring, any carbon in the ring could be your starting carbon. IUPAC naming likes to have the smallest numbers in their names, so you want to make that carbon attached to your substituent your first carbon in the Cyclohexane....

How would you go about doing the problem though? How can there be any equilibrium constant if all the products made in the slow reactions become reactants right away in the fast reaction?

Could you use the pre-equilibrium approach when the first step is slow or can you only use that approach when the second step is slow?

A small piece of sodium that lived in a test tube fell in love with a Bunsen burner. "Oh Bunsen, my flame," the sodium pined. "I melt whenever I see you," The Bunsen burner replied, "It's just a phase you're going through."

Hello,
I am currently enrolled in discussion 1L in Hardinger's 14C class. Would anyone want to switch with me?

Thank you.

The solution Manual used the formula Ecell = Cathode - anode. However, if you switched the sign for the anode and then added it to the cathode value then you would still get the same answer.

The delta T of the system would be zero if you are calculating the entire process: 290 to 295 to 290. Delta T = 290-290. If no work is done by the system during the heating and cooling, then Delta U = 0.

What effect does the being reversible vs irreversible have on entropy? How would you calculate both?

I do not believe that an O2 molecule would have a w=0. If you have one molecule of O2 at T=0 K, much like the problem in the course reader, there is only one possible position for such atom: O-O. 1 possible position and 1 atom would lead to w=1. However, with a degeneracy of 1, entropy would be 0. S...

On the course reader, you would have to compare the product bonds with the reactant bonds, finding out which ones stay intact and which ones are broken and then formed again. In that problem, one could see the double bond is broken and then formed as a single bond. Since we cannot calculate the ener...
