## dS = dq/T for irreversible processes

How can ds = dqr/T (d-bar q(reversible) / T) can be used to determine the entropy increase of a system in an irreversible process. Why does this technique works? Suppose some system undergoes an irreversible process. It was initially in some state of thermal equilibrium at some pressure volume, temperature (thermal equilibrium means simply that […]
