Textbook Question
Chapter 1.6, Problem 53P
Look up the enthalpy of formation of atomic hydrogen in the back of this book. This is the enthalpy change when a mole of atomic hydrogen is formed by dissociating 1/2 mole of molecular hydrogen (the more stable state of the element). From this number, determine the energy needed to dissociate a single H2 molecule, in electron-volts.

I need help solving number 11. In question 1, they say U=(3/2)PV
I found work on the gas as -3/2PV, so therefore Q should be 6/2PV but the answer key says 6PV.
The Type K thermocouple has a sensitivity of about 41 micro-Volts/℃, i.e. for each degree difference in the junction temperature, the output changes by 41 micro-Volts. If you have a 32-bit ADC, what is the smallest temperature change you can detect if the ADC range is 10 V? Try leaving the answer as a decimal with significant digits: e.g., 0.00004100.
In this and following questions, we develop a model for spontaneous
emission of a photon by a diatomic molecule AB (a model molecule),
which rotates and vibrates. In intermediate calculations, atomic units
(a.u.) will be used: unit of mass = the mass of electron, unit of charge
is the proton charge e, (e is a positive constant so that the charge of
electron is -e). The initial state of the molecule is an excited
rotational (1=1) and excited vibrational state (v=1). We consider a
molecule with the reduced mass µ = 10,000 a.u. (it is similar to the
mass of CO). After emitting a photon, the molecule will go to the 1=0,
v=0 state. The first question is about the model potential of the
molecule. It is represented by a potential of the form:
V(r)
=
C6
p12
C12
p6
"
where r is the distance between A and B in the molecule, C6 and C12
are positive constants (C6 =2 and C₁2-1). This potential has a well
meaning that the molecule is bound. The first thing to do is find
vibrational states of the…
