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

### Calculus on The Midterm

Will the midterm have problems where we use derivatives and integrals? In what problems would these be used.

### Re: Calculus on The Midterm

Right now, the only instance where we would have to use calculus is calculating the work done by reversible expansion, which is given by w = -(integral) Pdv. However, in many cases this can simplify to w= -nRTln(V2/V1), which is a simplified version of the integral that we can use if are given the number of moles and temperature of the reaction.

We aren't expected to go into this class with knowledge of calculus, so I don't think we will have to actually solve any integrals. Lavelle may, however, ask us to do a problem in a different way that will essentially give us the same answer an integral would – the area under a curve.

Hope this helped!

I believe the calculus would help understand problems but not needed!

I don't think its necessary, but I think he was trying to show how the equation is derived.

### Re: Calculus on The Midterm

the only calculus so far is w=integral(PdV)

I do believe calc is a pre/co req but I don't think we will need to do a lot of it. Especially on the midterm where other content will be covered like acids and bases and equilibrium

We aren't required to have previous knowledge of calculus so I don't think it will be on the exam.
