Assignment 1: Regular Assignment

A system initially containing 400 molecules of H2 and 100 molecule of D2 is allowed to equilibrate, forming HD. The most probable distribution in this case is 320 H2 + 20 D2 + 160 HD. The question is how probable is this most probable distribution?
 Suggested Method: List all the 101 distributions and determine the number of ways of getting each one. Adding all these ways together, we have the total number of ways possible. Then divide the number of ways of getting the most probable distribution by the total number of ways possible.

Assignment 2: Literature Report 

List all  Nobel laureates in Thermodynamics, along with their Nobel winning research work. Please mention which research work was in the regime of  'equilibrium thermo-dynamics' and which one was in the regime of 'non-equilibrium thermodynamics'.

Assignment 3: Interactive Assignment

"The most probable distribution of energy is the Boltzmann Distribution" - Justify.

Assignment 4: Regular Assignment 

Write a short note on "Negative Temperature".
Key Points:  zero temperature & negative temperatures - theoretical vs. experimental possibility, is negative temperature more "hotter" than positive temperature ?

Assignment 5: Reading Assignment

Measuring the heat associated with a chemical reaction experimentally requires carrying out the reaction in a device called Calorimeter. Study how the change in temperature of the calorimeter along with its heat capacity can be used to determine change in internal energy for a chemical reaction.
