HW 15.45
Is AB the intermediate just because it is formed in one reaction and then consumed in the other? There is still some form of it in step two products (A2B) so is it not completely consumed?

Re: 15.39
Hi, that is actually for part b and 0.37[A]initial comes from finding the moles total moles of A with the information give about concentration B.
Because A--> 2B + C so, [A]total= [A]initial-([B]x([A]/2[B])) to give you 0.055(mol A)/L which is equivalent to 0.37[A]initial
I hope that was helpful

Re: Vibrational Energy State
To add on to this heavier molecules have more vibrational energy states which means more disorder. As well as more complex molecules have more entropy or disorder.

Re: Work done by Reversible vs. Irreversible Reactions
A reversible process is slower so less of the energy is lost as heat. Where a irreversible process tends to generate more friction and more heat is lost to the surroundings.

Re: Positional Entropy
Hello!

Re: Internal Energy
Internal energy is the energy contained within a system. It accounts for the energy change in the systems internal state. So, that state can be changed by transfers of matter, heat or by doing work.
Enthalpy is equal to the internal energy of the system plus the product of pressure and volume.
