isothermal reversible expansion

Postby Marni Kahn 1A » Tue Feb 04, 2020 9:10 am

is the equation delta S=n*R*ln(v2/v1) only used when there has been an isothermal, reversible expansion reaction?

Yes, buy you are missing a T in your equation. The equation should be -nRTln(V2/V1)=Work of system.

Yes, when the reaction is isothermal and reversible, you use that equation to calculate the change in entropy of the system.
