### Positional Entropy or Thermal Entropy?

In class, Friday 1/20/17, we covered that $\Delta S= q/T$, is this formula used to find positional or thermal entropy?

### Re: Positional Entropy or Thermal Entropy?

I believe this equation is used to find positional/residual entropy in an isothermal system that has a reversible reaction, meaning no energy is transferred as heat and the reaction can go backwards.
