## work in reversible reaction

$w=-P\Delta V$
and
$w=-\int_{V_{1}}^{V_{2}}PdV=-nRTln\frac{V_{2}}{V_{1}}$

### work in reversible reaction

In $-\int _{V1}^{V2} PdV=-nRTln(V2/V1)$ what is d? Is it a separate variable or is it dV (the derivative of V) and how do you find it? Also do V1 and V2 represent volume? If they represent volume how do they turn into the number of microstates?

d represents the change in volume; V2=final volume; V1=initial volume

dV is a way of representing change in volume (this would be dV, the derivative of V, like you said). V2 and V1 represent the final and initial volumes, respectively. They do not represent microstates; I think you are confusing w (work) with W (degeneracy).

d is delta. In Calculus, it is the derivative. In this case, it is the change in volume.

Since we are deriving a change in volume volume known as delta the d is representative of that
