Question

The connection between the number of microstates, W, and the entropy, S, of a system is expressed by the Boltzmann equation s = k ln W where k is the Boltzmann constant per molecule (particle), 1.38 times 10-23 J/(K . particle). From this equation the entropy change, delta S, for a system can be related to the change in the number of microstates as delta s = k ln W final/W initial where Wfinal in the final number of microstates and W intial is the initial number of microstates? Express your answer numerically in jules per kelvin per articale.

Explanation / Answer

delta S = k.ln(wf/wi) = (1.38x10^-23)xln(0.614) = -6.73x10^-24 J/K.particle
