Electron Rearrangement
In reaction mechanisms, does the nucleophilic(electron rich) molecule go to the electrophilic(electron poor) molecule or is it the other way around?

Catalysts
Reactants sit on the surface of catalysts (adsorption), but can products sit on the surface as well?
Like on pg. 78, the NO is a reactant, then a product, then disappears. So when NO is on the product side and then disappears, does that mean products sit on the surface of the catalyst?

Slopes of the orders
Can there ever be a slope of 0? So the slope would just be --- instead of \ or /

Why is E not always equal to 0 V? Is there a specific instance where it can change?

Re: Higher molar heat capacity?
I believe C5H12 would have the higher molar heat capacity since there's more complexity and it takes more heat to increase its temperature.

Specific Heat Capacity-formula
For the specific heat capacity formula: (n)(Cp)(change in temperature), are you supposed to multiply the molar heat capacity by however many moles are included AND the temperature given, or are you supposed to multiply it by 1 mole and 25 degrees C so it is in the standard state?
