9.11

For chapter 9 question 11 it asks the entropy change with a change in pressure and given moles. What is the equation we use for this? Thanks!

I used the equation delta S=nRTln(P1/P2) since the pressure is changing and these is a constant temperature. You can substitute (T2/T1) for (P1/P2) using the ideal gas law.
