Final answer:
To calculate the entropy using the Boltzmann formula, multiply the number of molecules by the number of possible orientations and use the Boltzmann formula S = k * log(W), where S is the entropy, k is the Boltzmann constant, and W is the number of possible microstates.
Step-by-step explanation:
To calculate the entropy using the Boltzmann formula, we need to know the total number of possible orientations. In this case, each molecule can be oriented in any of six ways. The Boltzmann formula is given by S = k * log(W), where S is the entropy, k is the Boltzmann constant, and W is the number of possible microstates.
For 1.00 mol of chlorobenzene, we multiply the number of molecules by the number of possible orientations, giving us a total of 6 * 6.02 x 10^23 microstates. Plugging this value into the Boltzmann formula, along with the Boltzmann constant (k = 1.38 x 10^-23 J/K), we can calculate the entropy at t = 0.
