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

### Keywords for each equation

I'm still struggling to know when to use the correct equation, would someone mind sharing keywords they look for to determine which equation to use?

I know that I use the word "unique" to know if I have to use (-1/a)(dR/dt)

How do we apply the unique reaction rate?

The unique reaction rate tells how how much the reactant is being used in that specific equation (reliant on the coefficients).
