Activity 1: Counting Microstates and Calculating Probabilities If there is only one molecule of gas in the system (N=1), then there are 2 possible microstates for the system. If N=2, there are 4 possible microstates. This becomes easy to see if you think of all the possible ways to arrange the molecules and draw a diagram of each one, as shown below. N =1 moleye N = 2 1. In the space below, draw a sketch of all possible microstates for N = 3. Use different shapes or different colors so you can tell the particles apart. You should work it out on scratch paper first. What is the total number of microstates? 2. In the space below, draw a sketch of all possible microstates for N = 4. What is the total number of microstates? uodyot

Consider the reactionI2(g) + Cl2(g)-------2ICl(g)Using the standard thermodynamic data in the tables linked above, calculate the equilibrium constant for this reaction at 298.15K.ANSWER:
Use the References to access important values if needed for this question. For the reaction NH,Cl(aq)- NH3(g) + HCI(aq) AG° = 64.7 kJ and AH° =86.4 kJ at 274 K and 1 atm. This reaction is (reactant, product) favored under standard conditions at 274 K. The entropy change for the reaction of 2.44 moles of NH,Cl(aq) at this temperature would be J/K.
