change in entropy

Postby Tara_Hekmati_3B » Tue Jan 24, 2017 4:40 pm

Hi.
If delta S of a reversible system= q(reversible)/T, then does that mean for an irreversible system -q(irreversible)/T? If so, why or why not. Don't really understand the logic behind this equation.

Thank you.

Think about the difference between reversible and irreversible reaction's temperature. Reversible process has T(constant), what does irreversible pathways have?
