Entropy and multiplicity

Postby Cecilia Tsai 3C » Mon Feb 08, 2016 8:45 am

When solving for entropy, when do you use (to find W) 2^N and N!/n1!n2! ?

Thanks!

Multiplicity just informs you on the number of microstates for a particular configuration. So you would not be using multiplicity value for W (degeneracy), which gauges the total number of microstates available. S=klnW (where 2^Na) would only be used when there are two different states (ie. binding on/off receptor as mentioned in class) associated with a molar amount of some ligand for the receptor example.
