Relationship between activation energy and temperature
If the activation energy for a reaction is independent of temperature, how come we have the equation Ea= delta H + RT? Wouldn't an increase in temp cause an increase in the Ea?

Cholesterol example on page 84 of CR
The image of cholesterol on page 84 of the CR shows that most of the carbons in the molecule only have two or three bonds as opposed to four. Why is that?

Unique Rate of A Reaction
I see that 15.3 asks about the rate of the reaction in respect to different reactants. However, what do they mean when they refer to the unique rate of the reaction?

Basic Solution Redox Reaction
Are we expected to know basic solution redox reactions for the exam? Or will we only have to know how to deal with acidic solutions?

Sig Figs with Logs
Can anyone give a clear explanation of how many sig figs to use with logarithms? I am kind of confused by the information in the course reader.

Pressure's effect on Entropy
How does a change in pressure affect the entropy of a gas? Does it just depend on how the pressure change affects the volume and/or temperature?

Re: The Value of R
Basically just look at the units that you are are trying to solve for. For example, since this unit we are focusing a lot on energy, you will be using the R=8.314J/K*mol for a majority of the calculations because this value includes Joules. However, the other values of R are more helpful in using th...

Reversible vs. Irreversible Reactions
Can anyone give a good explanation as to why work done in a reversible reaction is always more than the work done in an irreversible reaction?
