| Jul 6, 2022 at 13:01 | comment | added | Chet Miller | Regarding you second question, no. dq for the system for the reversible path does not necessarily have to match dq for the system for the irreversible path. For example, for an adibatic irreversible process, dq is zero but dq between the same two end states for a reversible path is not. | |
| Jul 6, 2022 at 12:56 | comment | added | Chet Miller | To. get the changes in entropy of both system and surroundings for an irreversible process, you first separate them and then subject each to a separate reversible path. The reversible path for the system does not match the reversible path for the surroundings. Only the initial and final states have to match that of the irreversible path. | |
| Jul 6, 2022 at 11:03 | comment | added | Boson | Also, $dq_{sys, rev}=dq_{sys,irrev}$ in the entropy change of universe calculation, right? | |
| Jul 6, 2022 at 10:51 | comment | added | Boson | Just to clarify, you are saying $T_{sys}=T_{env}$ (where the temperature is taken at the boundary) in both reversible and irreversible but the value of temperature itself is different? | |
