### equation conversions

Can someone do a step-by-step breakdown of how to convert the equations for entropy between each other?

### Re: equation conversions

We start out with the equation
$\Delta S=q/T$
we will then have the equation
$w=-nRTln(V_2/V_1)$
since for an isothermal reaction we have
$q=-w$
Then we can sub in that for entropy and we will have the equation
$\Delta S=nRln(V_2/V_1)$
